feat: server-driven configurator settings via qt_settings

Replaces hardcoded JS category filters and config-type buttons with server-pushed settings synced from qt_settings (MariaDB) → local_qt_settings (SQLite). - new table local_qt_settings (AutoMigrate) — synced after component sync - GET /api/configurator-settings returns config_types, tab_config, always_visible_tabs, required_categories with hardcoded fallbacks - new-config modal: type buttons rendered from server data (Сервер/СХД static fallback) - configurator: TAB_CONFIG and category filter driven by server; required-category badge on tabs - SyncQtSettings wired into SyncComponents and SyncAll handlers (non-fatal on old server) - bible-local/server-contract-qt-settings.md — contract for server-side agent - page titles: OFS → QFS Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

+## 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.

+# 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`.
