feat: ревизия до обновления цен + короткие ссылки /:code для опти

- При нажатии «обновить цены» создаётся ревизия текущего состояния
  («до обновления цен») через новый эндпоинт POST /api/configs/:uuid/snapshot,
  затем saveConfig создаёт ревизию с новыми ценами
- Роут GET /:code → редирект на /projects/:uuid по коду опти (регистронезависимо)
- Валидация кода опти: только URL-безопасные символы [A-Za-z0-9._-]
  (бэкенд + клиентская проверка + подсказка в форме)

+# 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.

+# 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`.

+
+Дата релиза: 2026-06-16
+Тег: `v1.14`

+Предыдущий релиз: `v1.13`
+
+## Ключевые изменения
+
+- добавлен импорт человекочитаемого текстового BOM формата `<описание> - <кол-во> шт.`
+  (с необязательным заголовком, оканчивающимся на `, в составе:`) — как при загрузке файла
+  через `POST /api/projects/:uuid/vendor-import`, так и при вставке в конфигураторе;
+- заголовок конфигурации определяется по маркеру `, в составе:` с любым префиксом
+  (`Сервер X3` и `Вычислительный GPU сервер X3` → модель `X3`);
+- парсинг устойчив к пробелам в начале/конце строки (в P/N не попадает лишний пробел),
+  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;
+- сабмодуль `bible` обновлён до актуальных контрактов (build-version-display,
+  local-first-recovery, резервные копии миграций).
+
+## 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.

+
+## Ключевые изменения
+
+- self-heal застрявших pending changes: конфигурации со ссылкой на удалённый проект теперь автоматически переназначаются на «Без проекта» вместо вечной ошибки;
+- авторемонт очереди (`RepairPendingChanges`) запускается автоматически перед каждым push-циклом;
+- после 20 неудачных попыток неисправимые записи удаляются из очереди (логируются как ERROR);
+- неизвестные `entity_type` и `operation` в очереди дропаются с предупреждением вместо блокировки;
+- детальная диагностика в `qt_client_schema_state.last_sync_error_text`: теперь JSON-массив с `uuid`/`op`/`attempts`/`error` по каждому застрявшему изменению;
+- книги партномеров синхронизируются автоматически вместе с прайслистами.

+- BOM: поддержка формата `<qty>x <description>` при импорте Nx-спецификаций;
+- BOM: приоритет cart-LOT в дропдауне, корректный qtyMismatch при lot_qty_per_pn > 1;
+- CSV экспорт: bundle (1 PN → N LOT) разворачивается в отдельные строки;
+- ценообразование: ручная цена (buy/sale) сохраняется и экспортируется в CSV;

+
+## Что нового
+
+### Серверно-управляемые настройки конфигуратора
+
+Типы устройств, структура вкладок и фильтры категорий теперь приезжают с сервера вместо жёстко заданных JS-констант.
+
+- новая таблица `qt_settings` на стороне сервера (контракт в `bible-local/server-contract-qt-settings.md`);
+- QF синхронизирует `qt_settings` → `local_qt_settings` (SQLite) после каждой синхронизации компонентов;
+- новый endpoint `GET /api/configurator-settings` отдаёт четыре настройки: `config_types`, `tab_config`, `always_visible_tabs`, `required_categories`;
+- при недоступности сервера или отсутствии таблицы QF автоматически использует прежние захардкоженные значения — поведение не меняется.
+
+### Динамический выбор типа оборудования
+
+- модальное окно «Новая конфигурация» загружает типы устройств с сервера: названия и количество кнопок определяются в `qt_settings.config_types`;
+- добавление новых типов устройств не требует обновления QF.
+
+### Серверно-управляемая фильтрация категорий
+
+- конфигуратор фильтрует LOT-категории по списку из `qt_settings.config_types[].categories`;
+- структура вкладок обновляется из `qt_settings.tab_config` (порядок вкладок, подразделы, single-select режим);
+- бейдж на вкладке при незаполненных обязательных категориях (`qt_settings.required_categories`).
+
+### Прочее
+
+- тайтлы страниц переименованы с OFS на QFS.
