feat: redesign project pricing export — FOB/DDP basis, variant filename, article column

- Add FOB/DDP basis to export options; DDP multiplies all prices ×1.3
- Rename export file from "pricing" to "{FOB|DDP} {variant}" (e.g. "FOB v1")
- Fix server article missing from CSV summary row (PN вендора column)
- Skip per-row breakdown when neither LOT nor BOM is selected
- Remove empty separator rows between configurations
- Redesign export modal: split into Артикул / Цены / Базис поставки sections

-## Configuration types
-
-Configurations have a `config_type` field: `"server"` (default) or `"storage"`.
-
-Rules:
-- `config_type` defaults to `"server"` for all existing and new configurations unless explicitly set;
-- the configurator page is shared for both types; the SW tab is always visible regardless of type;
-- storage configurations use the same vendor_spec + PN→LOT + pricing flow as server configurations;
-- storage component categories map to existing tabs: `ENC`/`DKC`/`CTL` → Base, `HIC` → PCI (HIC-карты СХД; `HBA`/`NIC` — серверные, не смешивать), `SSD`/`HDD` → Storage (используют существующие серверные LOT), `ACC` → Accessories (используют существующие серверные LOT), `SW` → SW.
-- `DKC` = контроллерная полка (модель СХД + тип дисков + кол-во слотов + кол-во контроллеров); `CTL` = контроллер (кэш + встроенные порты); `ENC` = дисковая полка без контроллера.
-- the available config types and their localized names flow from `qt_settings.config_types` on the server;
-  QF falls back to hardcoded "server/Сервер" and "storage/СХД" when the setting is absent.
-
-## Server-driven configurator settings (`qt_settings`)
-
-QF reads four settings from `qt_settings` (MariaDB) and caches them in `local_qt_settings` (SQLite).
-They are synced during every component sync. See `bible-local/server-contract-qt-settings.md` for the
-full contract and JSON schemas.
-
-| Setting key | Effect in QF |
-|-------------|-------------|
-| `config_types` | New-config modal buttons; category allowlist per config type |
-| `tab_config` | Configurator tab structure, sections, singleSelect |
-| `always_visible_tabs` | Which tabs are shown even when empty |
-| `required_categories` | Per-config-type badge on tabs with unfilled required categories |
-
-Rules:
-- sync runs after `SyncComponents`; failure is non-fatal (Warn log only);
-- `local_qt_settings` is a read-only cache — never written by user actions;
-- absent or unparseable settings: QF uses hardcoded fallbacks for that key only;
-- `config_types[].categories` is an allowlist: a category absent from all types is shown everywhere;
-- `qt_categories.name` and `qt_categories.name_ru` are not used by QF runtime; do not depend on them.

-
-`POST /api/vendor-spec/parse-text` is a stateless endpoint that parses pasted single-column text BOM
-(Inspur and Russian text BOM) into rows. Request body: `{"text": "..."}`. Response:
-`{"rows": [{vendor_partnumber, quantity, description}], "format": "Inspur"|"Text"|""}`.
-
-This shares the exact detectors and parsers used by the file-import path
-(`ParsePastedBOMText` → `IsInspurBOM`/`parseInspurBOM`, `IsNxBOM`/`parseNxBOM`, `IsTextBOM`/`parseTextBOM`),
-so paste and upload behave identically — there is no second parser in the frontend. The configurator's BOM
-paste box calls this endpoint; an empty `rows` result (or any payload containing tabs, i.e. a real
-spreadsheet table) falls back to the manual column-mapping grid.

-# 10 - Agent API Guide: Pricing Servers from a TZ
-
-This guide is written for an AI agent that needs to price a server configuration
-(техническое задание, ТЗ) using the QuoteForge HTTP API.
-
-## Runtime assumptions
-
-- QuoteForge runs locally, binds to `127.0.0.1:8080` by default.
-- No authentication is required — the app is single-user, loopback-only.
-- All responses are JSON. All request bodies are JSON unless stated otherwise.
-- The port can be overridden with the `QF_SERVER_PORT` environment variable.

-## Configuration composition rules
-
-These rules are mandatory and must be respected before saving any configuration.
-
-### 1. Every configuration must belong to a project
-
-Configurations cannot be created in isolation. The correct sequence is:
-
-1. Create a project (`POST /api/projects`) and save the returned `uuid`.
-2. Create the configuration inside that project by passing `project_uuid` in the
-   config body, or by using `POST /api/projects/:uuid/configs`.
-
-If the project for a given TZ already exists, retrieve its `uuid` first:
-```
-GET /api/projects?page=1&per_page=100
-```
-then pass the matching `uuid` in `project_uuid`.
-
-### 2. Every server configuration must contain all four required component groups
-
-A configuration is not valid for pricing unless items from all four of the
-following category groups are present:
-
-| Category code | Meaning          | Notes                                             |
-|---------------|------------------|---------------------------------------------------|
-| `MB`          | Motherboard      | exactly one MB per configuration                  |
-| `CPU`         | Processor        | one or more CPUs                                  |
-| `MEM`         | Memory / RAM     | one or more memory modules                        |
-| `PS` / `PSU`  | Power supply     | `PSU` is the current code; `PS` is legacy — both are accepted |
-
-Before saving, verify the assembled BOM with `POST /api/quote/validate`:
-the response `errors` array will contain `"Component not found: …"` entries
-for unknown lot names, and `warnings` will list lots without a price.
-Reject the configuration and report back to the user if any of the four
-required categories is missing.
-
-### 3. Category codes to use when searching
-
-Use `category=<code>` in `GET /api/components` to narrow results:
-
-```
-GET /api/components?category=MB&search=X13&has_price=true
-GET /api/components?category=CPU&search=Xeon+Gold&has_price=true
-GET /api/components?category=MEM&search=32GB+DDR5&has_price=true
-GET /api/components?category=PSU&search=800W&has_price=true
-```
-
-Retrieve the full list of active categories at any time:
-```
-GET /api/categories
-```
-
----
-
-## Typical workflow for pricing a server
-
-```
-1.  Check the app is up                 GET  /api/ping
-2.  Find or create a project            GET  /api/projects  →  POST /api/projects
-3.  Find the latest pricelist           GET  /api/pricelists/latest?source=estimate
-4.  Look up lot names for MB            GET  /api/components?category=MB&search=…
-5.  Look up lot names for CPU           GET  /api/components?category=CPU&search=…
-6.  Look up lot names for MEM           GET  /api/components?category=MEM&search=…
-7.  Look up lot names for PSU           GET  /api/components?category=PSU&search=…
-8.  (Repeat for other components)       GET  /api/components?category=…&search=…
-9.  Validate and calculate the quote    POST /api/quote/validate

-
-## Step 3 — Find the latest pricelist
-
-QuoteForge maintains three pricing tiers. The `source` values are:
-
-| source       | meaning                     |
-|--------------|-----------------------------|
-| `estimate`   | list / catalogue price      |
-| `warehouse`  | stock price (purchase cost) |
-| `competitor` | competitor reference price  |
-
-```
-GET /api/pricelists/latest?source=estimate
-```
-
-Response `200 OK`:
-```json
-{
-  "id": 42,
-  "source": "estimate",
-  "version": "2026-05-28",
-  "item_count": 12500,
-  "is_active": true,
-  "created_at": "2026-05-28T06:00:00Z"
-}
-```
-
-The `id` field is a numeric pricelist identifier. Pass it as `pricelist_id`
-when calculating a quote to pin pricing to a specific pricelist.
-
-To list all available pricelists:
-```
-GET /api/pricelists?source=estimate&active_only=true
-```
-
----
-
-## Steps 4–8 — Look up component lot names
-
-Each component is identified by a `lot_name` (internal SKU). The TZ typically
-contains model names or descriptions; use the search endpoint to resolve them.
-
-```
-GET /api/components?search=Xeon+Gold+6342&category=CPU&has_price=true&page=1&per_page=20
-```
-
-Query parameters:
-
-| parameter        | default | description                                       |
-|------------------|---------|---------------------------------------------------|
-| `search`         | —       | free-text search in lot name and description      |
-| `category`       | —       | filter by category code (`MB`, `CPU`, `MEM`, `PSU`, …) |
-| `has_price`      | false   | return only components that have a price          |
-| `include_hidden` | false   | include hidden/retired components                 |
-| `page`           | 1       | page number                                       |
-| `per_page`       | 20      | page size                                         |
-
-Response `200 OK`:
-```json
-{
-  "components": [
-    {
-      "lot_name": "CPU-XEON-6342",
-      "description": "Intel Xeon Gold 6342, 24C/48T, 2.8 GHz, LGA4189",
-      "category": "CPU",
-      "category_name": "CPU",
-      "model": "Xeon Gold 6342"
-    }
-  ],
-  "total": 1,
-  "page": 1,
-  "per_page": 20
-}
-```
-
-To look up a single component by exact lot name:
-```
-GET /api/components/CPU-XEON-6342
-```
-
-To list all known categories:
-```
-GET /api/categories
-```
-
----
-
-## Step 9 — Validate and calculate the quote
-
-Before saving, validate the assembled BOM. This catches unknown lot names and
-missing prices, and also confirms that all required categories are covered.
-
-```
-POST /api/quote/validate
-Content-Type: application/json
-```
-
-Request body:
-```json
-{
-  "items": [
-    {"lot_name": "MB-X13DAI-N",        "quantity": 1},

-    {"lot_name": "RAM-32GB-DDR4-3200",  "quantity": 8},
-    {"lot_name": "SSD-480GB-SATA",      "quantity": 2},
-    {"lot_name": "PSU-800W-TITANIUM",   "quantity": 2}
-  ],
-  "pricelist_id": 42
-}
-```
-
-Response `200 OK`:
-```json

-      "category": "PSU",
-      "has_price": true
-    }
-  ],
-  "errors": [],
-  "warnings": [],
-  "total": 403000.00
-}
-```
-
-**Agent check after validation:**
-
-1. `valid` must be `true` — all lot names resolved.
-2. `errors` must be empty — no unknown components.
-3. The returned `items` array must contain at least one entry from each required
-   category: `MB`, `CPU`, `MEM`, and `PS` or `PSU`.
-4. Items with `has_price: false` are allowed but should be flagged to the user.
-
-If any check fails, do not save the configuration. Report the issue and ask the
-user to clarify or replace the problematic component.
-
-For simple price totals without validation metadata use `POST /api/quote/calculate`
-— identical request body, response contains only `items` and `total`.
-
----
-
-## Step 10 (optional) — Compare price tiers
-
-To see estimate, warehouse, and competitor prices side-by-side for a BOM:
-
-```
-POST /api/quote/price-levels
-Content-Type: application/json
-```
-
-Request body:
-```json
-{
-  "items": [
-    {"lot_name": "CPU-XEON-6342", "quantity": 2},
-    {"lot_name": "RAM-32GB-DDR4-3200", "quantity": 8}
-  ],
-  "pricelist_ids": {
-    "estimate": 42,
-    "warehouse": 31,
-    "competitor": 15
-  },
-  "no_cache": false
-}
-```
-
-`pricelist_ids` is optional. When omitted the latest pricelist for each source
-is used automatically.
-
-Response `200 OK`:
-```json
-{
-  "items": [
-    {
-      "lot_name": "CPU-XEON-6342",
-      "quantity": 2,
-      "estimate_price": 87500.00,
-      "warehouse_price": 71000.00,

-  "resolved_pricelist_ids": {
-    "estimate": 42,
-    "warehouse": 31,
-    "competitor": 15

-}
-```
-
-`price_missing` lists the source names for which no price was found for that lot.
-Delta fields are `null` when either operand price is missing.
-
----
-
-## Step 11 — Save a configuration inside the project
-
-Use the project-scoped endpoint so the configuration is immediately linked to
-the correct project without a separate move operation.
-
-```
-POST /api/projects/:project_uuid/configs
-Content-Type: application/json
-```
-
-The request body is identical to `POST /api/configs` — the `project_uuid` field
-in the body is ignored when using the project-scoped route; the URL parameter
-takes precedence.

-# 11 - Lot Suggestions (qt_vendor_partnumber_seen)
-
-## Purpose
-
-`qt_vendor_partnumber_seen` records vendor partnumbers encountered during import
-that have no mapping in the active partnumber book. When a user manually maps
-such a partnumber to one or more LOT names in the QuoteForge UI, those mappings
-are written back to the server as **lot suggestions** — hints for the team that
-maintains `qt_partnumber_book_items`.
-
-## Schema Extension
-
-Add one nullable column to `qt_vendor_partnumber_seen`:
-
-```sql
-ALTER TABLE `qt_vendor_partnumber_seen`
-  ADD COLUMN `lot_suggestion` longtext DEFAULT NULL
-    COMMENT 'JSON array [{lot_name, qty}] — user-entered LOT mappings from the UI';
-```
-
-### Updated table contract (relevant columns only)
-
-| Column | Type | Notes |
-|--------|------|-------|
-| `partnumber` | varchar(255) UNIQUE NOT NULL | natural key |
-| `lot_suggestion` | longtext (JSON) | nullable; set when user maps the PN manually |
-
-`lot_suggestion` contains the same JSON shape as `qt_partnumber_book_items.lots_json`:
-
-```json
-[
-  { "lot_name": "LOT_A", "qty": 1 },
-  { "lot_name": "LOT_B", "qty": 2 }
-]
-```
-
-Rules:
-- `null` or absent means no suggestion has been entered yet;
-- an empty array `[]` is not a valid value — use `null` instead;
-- a single PN may map to multiple lots (`lot_name` entries), each with its own `qty`;
-- the array is ordered — the order reflects the order of `lot_mappings[]` in the
-  vendor spec row at the time of last user save;
-- `qty` must be a positive integer (≥ 1).
-
-## Write Contract (QuoteForge → MariaDB)
-
-QuoteForge writes `lot_suggestion` when all of the following are true:
-
-1. The user saves a vendor BOM via `PUT /api/configs/:uuid/vendor-spec`.
-2. At least one `vendor_spec` row has a non-empty `lot_mappings[]` array (manually
-   entered or confirmed by the user — not auto-resolved from a partnumber book).
-3. The MariaDB connection is available at the time of save.
-
-For each such row:
-
-```sql
-INSERT INTO qt_vendor_partnumber_seen
-    (source_type, vendor, partnumber, description, is_ignored, last_seen_at, lot_suggestion)
-VALUES
-    ('manual', '', ?, ?, 0, NOW(3), ?)
-ON DUPLICATE KEY UPDATE
-    lot_suggestion = VALUES(lot_suggestion),
-    last_seen_at   = IF(lot_suggestion IS NULL, last_seen_at, NOW(3))
-```
-
-- `lot_suggestion` value = JSON-marshalled `lot_mappings[]` from the vendor spec item,
-  reusing the same `{lot_name, qty}` shape.
-- If the PN row already exists and `lot_suggestion` is already set, it is **overwritten**
-  with the latest user input (the user is assumed to have corrected it).
-- If the user **clears** all lot_mappings for a PN (sets to empty), no update is sent —
-  the existing `lot_suggestion` on the server is left untouched.
-- Rows where `lot_mappings[]` is empty or nil are skipped entirely (no insert, no update).
-- Writes are best-effort: a MariaDB error for one row is logged and skipped; remaining
-  rows continue. A write failure does not fail the vendor-spec save.
-
-## Read Contract (Partnumber-Book Creation Tool → MariaDB)
-
-The tool that maintains `qt_partnumber_book_items` reads `qt_vendor_partnumber_seen`
-to discover new partnumbers and their suggested mappings.
-
-### Discovery query
-
-```sql
-SELECT
-    s.id,
-    s.partnumber,
-    s.description,
-    s.vendor,
-    s.lot_suggestion,
-    s.last_seen_at,
-    b.lots_json AS book_lots_json
-FROM qt_vendor_partnumber_seen s
-LEFT JOIN qt_partnumber_book_items b ON b.partnumber = s.partnumber
-WHERE s.is_ignored = 0
-  AND s.lot_suggestion IS NOT NULL
-ORDER BY s.last_seen_at DESC;
-```
-
-### Interpretation rules
-
-| Condition | Meaning | Suggested action |
-|-----------|---------|-----------------|
-| `book_lots_json IS NULL` AND `lot_suggestion IS NOT NULL` | No book entry yet; user suggested mapping | Create new `qt_partnumber_book_items` row with `lots_json = lot_suggestion` |
-| `book_lots_json IS NOT NULL` AND `lot_suggestion IS NOT NULL` AND they differ | User corrected or extended the existing mapping | Review diff and decide whether to update `qt_partnumber_book_items` |
-| `book_lots_json IS NOT NULL` AND `lot_suggestion IS NOT NULL` AND they match | Suggestion already applied | No action needed |
-
-### Suggestion format
-
-`lot_suggestion` is valid JSON (or `null`). Parse it as an array of objects:
-
-```json
-[
-  { "lot_name": "LOT_A", "qty": 1 },
-  { "lot_name": "LOT_B", "qty": 2 }
-]
-```
-
-Map directly to `qt_partnumber_book_items.lots_json` — the formats are identical.
-
-### Multiple lots per PN
-
-One PN may have multiple suggestion entries (e.g., a bundle). The array carries
-all of them. The book-creation tool must preserve the full array when writing
-`lots_json`, not just the first element.
-
-### Qty semantics
-
-`qty` in a lot suggestion means "how many of this LOT per one occurrence of the
-vendor PN". This matches `qt_partnumber_book_items.lots_json` exactly. Example:
-a server platform that comes with 4 PSUs would produce
-`[{"lot_name": "PS_1300W_Titanium", "qty": 4}]`.
-
-## Permissions
-
-The existing `qfs_user` grant covers this column — no new permission is required:
-
-```sql
-GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_vendor_partnumber_seen TO 'qfs_user'@'%';
-```
-
-The book-creation tool connects with its own credentials and needs at minimum:
-
-```sql
-GRANT SELECT ON RFQ_LOG.qt_vendor_partnumber_seen TO '<book_tool_user>'@'%';
-GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_partnumber_book_items TO '<book_tool_user>'@'%';
-```
-
-## Migration
-
-Migration is applied outside this repo (server-side DDL):
-
-```sql
-ALTER TABLE `qt_vendor_partnumber_seen`
-  ADD COLUMN IF NOT EXISTS `lot_suggestion` longtext DEFAULT NULL
-    COMMENT 'JSON [{lot_name, qty}] — user LOT suggestions from QuoteForge UI';
-```
-
-QuoteForge handles a missing column gracefully: if the migration has not run yet,
-the write with `lot_suggestion` fails with "Unknown column" (MariaDB 1054), a warning
-is logged, and the row is re-inserted without the column. The app never crashes on
-migration lag.

-# Runtime Flows
-
-Critical mutation paths, deduplication logic, and cross-entity side effects.
-Update this file in the same commit as any change to the flows below.
-
----
-
-## 1. Configuration save (create/update)
-
-1. Handler receives JSON body; validates via `ShouldBindJSON`.
-2. `LocalConfigurationService.Create` or `Update` is called.
-3. Service computes `total_price` from `req.Items.Total()` (sum of `unit_price * quantity` per item).
-4. A new revision snapshot is created via `createWithVersion`; revision number increments.
-5. `quoteService.RecordUsage` is called best-effort (warn on failure, do not abort save).
-6. Configuration row written to SQLite (`local_configurations`); version row appended to `local_configuration_versions`.
-7. Pending change queued in `pending_changes` for later sync push.
-
-**DO NOT** read prices from `local_components` during save - prices must already be on items.
-**DO NOT** skip version creation on rename/reorder/project-move - those operations call different paths that must NOT call `createWithVersion`.
-
----
-
-## 2. Refresh prices (POST /api/configs/:uuid/refresh-prices)
-
-1. Handler calls `LocalConfigurationService.RefreshPricesNoAuth(uuid, pricelistServerID)`.
-2. If online, `SyncPricelistsIfNeeded` runs best-effort (warn on failure, do not block).
-3. Resolves target pricelist in order:
-   a. Explicitly requested pricelist (`pricelistServerID` param).
-   b. Pricelist stored in configuration row (`localCfg.PricelistID`).
-   c. Latest local pricelist as fallback.
-4. For each item in the config, looks up price from `local_pricelist_items` via `GetLocalPricesForLots` (batch, single query).
-5. Items with matching prices are updated; items with no price keep their existing `unit_price`.
-6. Updated configuration saved as a new version (same flow as §1 from step 4 onward).
-
-**DO NOT** read prices from `qt_pricelist_items` (MariaDB) directly - prices come from SQLite cache only.
-
----
-
-## 3. Pricelist sync (POST /api/sync/pricelists)
-
-1. Readiness guard checked; returns 423 if guard blocks sync.
-2. `SyncService.SyncPricelists` pulls from `qt_pricelists` and `qt_pricelist_items` (MariaDB).
-3. For each pricelist: header upserted first, then items replaced atomically via `ReplaceLocalPricelistItems`.
-4. After all pricelists: `RecalculateAllLocalPricelistUsage` marks which pricelists are referenced by active configurations.
-5. Sync result (status, error, timestamp) written to `app_settings` via `SetPricelistSyncResult`.
-
-**DO NOT** write pricelist header without items in the same transaction - must be atomic.
-**DO NOT** query MariaDB from runtime handlers outside sync/setup flows.
-
----
-
-## 4. Vendor spec apply (POST /api/configs/:uuid/vendor-spec/apply)
-
-1. Incoming `items[]` (lot_name, quantity, unit_price) replace the configuration's `items` entirely.
-2. New item list saved through `LocalConfigurationService.UpdateItemsNoAuth`.
-3. A new revision is created reflecting the BOM-derived item state.
-
-**DO NOT** apply vendor spec without going through the service layer - handler must not write items directly to DB.
-
----
-
-## 5. Configuration versioning invariants
-
-- `local_configuration_versions` is append-only; rows are never updated or deleted.
-- Version deduplication: if new snapshot hash equals current head, no new version is created.
-- Rollback = create new HEAD revision from old snapshot data (does not restore version pointer to old row).
-- UI must always show "main" (implicit head) as the active state; never point to a numbered revision after save.
-- Operations that do NOT create a new version: rename, reorder within project, project move, pricelist selector change only.
-
----
-
-## 6. Pending changes queue
-
-- Every local write (create/update/delete) appends a row to `pending_changes`.
-- `POST /api/sync/push` drains the queue by writing to MariaDB.
-- If a push fails, `increment_attempts` and `last_error` are updated; row stays in queue.
-- `RepairPendingChanges` reconciles orphaned changes (configuration/project deleted locally).
-
----
-
-## 7. Error handling boundary rules
-
-- Handlers: log 500 responses with `slog.Error`; surface error message via `RespondError`.
-- Services: wrap errors with `fmt.Errorf("context: %w", err)`; do NOT log inside service.
-- Repositories: return raw errors; no logging.
-- Best-effort operations (usage stats, background sync): log `slog.Warn` and continue.

-# Server contract: qt_settings
-
-## Purpose
-
-`qt_settings` is a general-purpose key→JSON-value table that the price management
-application uses to push configuration into QuoteForge clients. QF reads it during
-component sync and caches the result in `local_qt_settings` (SQLite).
-
-## Required MariaDB changes (implemented by server-side agent)
-
-```sql
-CREATE TABLE IF NOT EXISTS qt_settings (
-    name  VARCHAR(100) NOT NULL PRIMARY KEY,
-    value TEXT         NOT NULL   -- JSON-encoded value
-) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;
-
-GRANT SELECT ON RFQ_LOG.qt_settings TO 'qfs_user'@'%';
-```
-
-## Settings consumed by QuoteForge
-
-All values are JSON. Missing or unparseable entries are silently skipped; QF
-falls back to hardcoded defaults for each missing key.
-
----
-
-### `config_types`
-
-Defines the available device configuration types, their localized names, and the
-category codes that are allowed for each type. QF uses this for:
-- the new-config modal (button list + labels);
-- the configurator's category filter per `config_type`.
-
-**Value format:** JSON array of objects.
-
-```json
-[
-  {
-    "code":          "server",
-    "name_ru":       "Сервер",
-    "display_order": 10,
-    "categories":    [
-      "MB","CPU","MEM","RAID",
-      "SSD","HDD","M2","EDSFF","HHHL",
-      "GPU","NIC","HCA","DPU","HBA",
-      "PSU","PS","ACC","RISERS","CARD","BB"
-    ]
-  },
-  {
-    "code":          "storage",
-    "name_ru":       "СХД",
-    "display_order": 20,
-    "categories":    [
-      "DKC","CPU","MEM","PS",
-      "SSD","HDD","M2","EDSFF","HHHL",
-      "NIC","HBA","HCA","ACC","CARD"
-    ]
-  }
-]
-```
-
-Fields:
-| Field | Type | Description |
-|-------|------|-------------|
-| `code` | string | Identifier stored on `qt_configurations.config_type`. Must be stable. |
-| `name_ru` | string | Display name in Russian for the QF UI. |
-| `display_order` | int | Sort order for the modal button list. |
-| `categories` | string[] | Allowlist of LOT category codes visible in this config type. A category absent from ALL entries is visible in all types. |
-
----
-
-### `tab_config`
-
-Defines the configurator tab layout: which tabs exist, which categories each tab
-contains, optional sub-sections within a tab, and whether the tab uses
-single-select mode.
-
-**Value format:** JSON array of tab objects (ordered — defines tab bar order).
-
-```json
-[
-  {
-    "key":           "base",
-    "label":         "Base",
-    "single_select": true,
-    "categories":    ["MB","CPU","MEM","ENC","DKC","CTL"],
-    "sections":      null
-  },
-  {
-    "key":           "storage",
-    "label":         "Storage",
-    "single_select": false,
-    "categories":    ["RAID","M2","SSD","HDD","EDSFF","HHHL"],
-    "sections": [
-      { "title": "RAID Контроллеры", "categories": ["RAID"] },
-      { "title": "Диски",            "categories": ["M2","SSD","HDD","EDSFF","HHHL"] }
-    ]
-  },
-  {
-    "key":           "pci",
-    "label":         "PCI",
-    "single_select": false,
-    "categories":    ["GPU","DPU","NIC","HCA","HBA","HIC"],
-    "sections": [
-      { "title": "GPU / DPU", "categories": ["GPU","DPU"] },
-      { "title": "NIC / HCA", "categories": ["NIC","HCA"] },
-      { "title": "HBA",       "categories": ["HBA"] },
-      { "title": "HIC",       "categories": ["HIC"] }
-    ]
-  },
-  { "key": "power",       "label": "Power",       "single_select": false, "categories": ["PS","PSU"] },
-  { "key": "accessories", "label": "Accessories", "single_select": false, "categories": ["ACC","CARD"] },
-  { "key": "sw",          "label": "SW",          "single_select": false, "categories": ["SW"] }
-]
-```
-
-The QF frontend always appends an "other" tab for any categories not listed here.
-
----
-
-### `always_visible_tabs`
-
-Tab keys that are always shown in the configurator regardless of whether they
-contain any items. Other tabs are hidden when empty.
-
-**Value format:** JSON string array.
-
-```json
-["base", "storage", "pci"]
-```
-
----
-
-### `required_categories`
-
-Category codes that must have at least one LOT selected for a configuration to
-be considered complete. Keyed by `config_type` code. QF uses this to show a
-badge on the tab label when required categories are missing.
-
-**Value format:** JSON object mapping config_type code → string array.
-
-```json
-{
-  "server":  ["CPU", "MEM", "BB"],
-  "storage": ["DKC", "CPU", "MEM"]
-}
-```
-
----
-
-## Backward compatibility
-
-- If `qt_settings` does not exist (old server): QF logs `Warn` during sync and
-  leaves `local_qt_settings` empty. The frontend falls back to hardcoded defaults
-  for all four settings. No crash, no data loss.
-- If a specific key is absent from `qt_settings`: QF falls back to the hardcoded
-  default for that key only.
-- Old QF clients that do not know about `local_qt_settings` continue to use their
-  hardcoded JS constants unchanged.
-
-## Note on `qt_categories`
-
-`qt_categories.name` and `qt_categories.name_ru` are being removed.
-QF runtime does not depend on them — `GetCategories` derives `Name` from the
-category code string stored in `local_components`.

-## Что такое LOT и зачем он нужен
-
-LOT — это внутренний идентификатор типа компонента в системе QuoteForge.
-
-Каждый LOT представляет одну рыночную позицию и хранит **средневзвешенную рыночную цену**, рассчитанную по историческим данным от поставщиков. Это позволяет получать актуальную оценку стоимости независимо от конкретного поставщика или прайс-листа.
-
-Партномера вендора (Part Number, Feature Code) сами по себе не имеют цены в системе — они **переводятся в LOT** через книгу партномеров. Именно через LOT происходит расценка конфигурации.
-
-**Пример:** Feature Code `B4B9` и Part Number `4C57A14368` — это два разных обозначения одной и той же HIC-карты от Lenovo. Оба маппируются на один LOT `HIC_4pFC32`, у которого есть рыночная цена.

-
-Категория LOT определяет, в какой вкладке конфигуратора он появится.
-
-| Код категории | Название | Вкладка | Что сюда относится |
-|---|---|---|---|
-| `ENC` | Storage Enclosure | **Base** | Дисковая полка без контроллера |
-| `DKC` | Disk/Controller Enclosure | **Base** | Контроллерная полка: модель СХД + тип дисков + кол-во слотов + кол-во контроллеров |
-| `CTL` | Storage Controller | **Base** | Контроллер СХД: объём кэша + встроенные хост-порты |
-| `HIC` | Host Interface Card | **PCI** | HIC-карты СХД: интерфейсы подключения (FC, iSCSI, SAS) |
-| `HDD` | HDD | **Storage** | Жёсткие диски (HDD) |
-| `SSD` | SSD | **Storage** | Твердотельные диски (SSD, NVMe) |
-| `ACC` | Accessories | **Accessories** | Кабели подключения, кабели питания |

-## Правила именования LOT
-
-Формат: `КАТЕГОРИЯ_МОДЕЛЬСХД_СПЕЦИФИКА`
-
-- только латиница, цифры и знак `_`
-- регистр — ВЕРХНИЙ
-- без пробелов, дефисов, точек
-- каждый LOT уникален — два разных компонента не могут иметь одинаковое имя

-## Что нового
-
-### Новые возможности
-
-- **Support Bundle** — кнопка-иконка в шапке рядом с именем пользователя скачивает ZIP-архив с диагностикой: версия приложения, статистика локальной БД, статус подключения с TCP-пингом до сервера, история синхронизаций (`sync_log`), список скачанных прайслистов, системные метрики (память, диск), состояние readiness-блокировки и лог-файл приложения.
-- **Автосинхронизация компонентов** — при первом запуске с пустой таблицей компонентов фоновый воркер автоматически скачивает каталог из MariaDB. Новые пользователи сразу видят все вкладки и автокомплит артикулов без ручной синхронизации.
-- **Импорт собственного CSV QuoteForge** — файлы, экспортированные из QuoteForge, можно импортировать обратно в конфигурацию.
-- **Кнопка «Обновить цены» на странице варианта проекта** — обновление цен доступно прямо со страницы проекта.
-- **Импорт BOM Inspur в формате PN×qty** — поддержка формата `артикул × количество` при импорте Inspur-спецификаций.
-
-### Исправления
-
-- **«Не докачано» исчезает когда всё на месте** — исправлена логика `NeedSync`: при наличии подключения всегда сравниваем реальные версии с сервером, не ориентируясь на давность последнего синка. Устраняет ситуацию когда бейдж висел вечно после сетевого сбоя, хотя все прайслисты уже были скачаны.
-- **Синхронизация прайслистов через медленное соединение** — увеличен `WriteTimeout` с 30 с до 10 мин. При высокой задержке до сервера (VPN, >300 мс) кнопка «Синхронизировать» больше не зависает без обратной связи.
-- **ALTER-спам в логах** — устранены повторяющиеся WARN `ALTER command denied` каждые 5 минут. DDL на `qt_client_schema_state` выполняется не более одного раза за жизнь процесса и только если колонки реально отсутствуют.
-- **Галочка «Создать копию»** включена по умолчанию в обоих диалогах клонирования.
-- **Сортировка категорий в CSV-экспорте** — исправлена сортировка без учёта регистра и правильный порядок (MB → CPU → MEM → RAID → диски → GPU → NIC → HBA → PSU → ACC).
-- **`/api/categories` возвращал `display_order: 0`** для всех категорий — исправлено.
-
-## Для администраторов
-
-При обновлении с v1.9 выполните миграцию на сервере:
-
-```bash
-go run ./cmd/qfs -migrate
-```
-
-Это добавит колонку `hostname` в `qt_client_schema_state`, после чего клиентские приложения перестанут получать ошибку `ALTER command denied`.
-
-## Запуск на macOS
-
-Снимите карантинный атрибут через терминал: `xattr -d com.apple.quarantine /path/to/qfs-darwin-arm64`  
-После этого бинарник запустится без предупреждения Gatekeeper.

-  (с необязательным заголовком, оканчивающимся на `, в составе:`) — как при загрузке файла

-  а также к запятым и дефисам внутри описания (`RAID0,1,10`, `8-GPU-2304GB`);
-- вставка BOM в конфигураторе и импорт файла используют единый серверный парсер
-  (`POST /api/vendor-spec/parse-text`) — дублирующая логика разбора на фронтенде удалена;
