Root cause: Projects with duplicate (code, variant) pairs fail to sync
due to unique constraint on server. Example: multiple "OPS-1934" projects
with variant="Dell" where one already exists on server.
Fixes:
1. Sync service now detects duplicate (code, variant) on server and links
local project to existing server project instead of failing
2. Local repair checks for duplicate (code, variant) pairs and deduplicates
by appending UUID suffix to variant
3. Modal now scrollable with fixed header/footer (max-h-90vh)
This allows users to sync projects that were created offline with
conflicting codes/variants without losing data.

Implements automatic repair mechanism for pending changes with sync errors:
- Projects: validates and fixes empty name/code fields
- Configurations: ensures project references exist or assigns system project
- Clears errors and resets attempts to give changes another sync chance
Backend:
- LocalDB.RepairPendingChanges() with smart validation logic
- POST /api/sync/repair endpoint
- Detailed repair results with remaining errors
Frontend:
- Auto-repair section in sync modal shown when errors exist
- "ИСПРАВИТЬ" button with clear explanation of actions
- Real-time feedback with result messages

Fixed application freezing in offline mode by preventing unnecessary
reconnection attempts:
**Changes:**
1. **DSN timeouts** (localdb.go)
- Added timeout=3s, readTimeout=3s, writeTimeout=3s to MySQL DSN
- Reduces connection timeout from 75s to 3s when MariaDB unreachable
2. **Fast /api/db-status** (main.go)
- Check connection status before attempting GetDB()
- Avoid reconnection attempts on every status request
- Returns cached offline status instantly
3. **Optimized sync service** (sync/service.go)
- GetStatus() checks connection status before GetDB()
- NeedSync() skips server check if already offline
- Prevents repeated 3s timeouts on every sync info request
4. **Local pricelist fallback** (pricelist.go)
- GetLatest() returns local pricelists when server offline
- UI can now display pricelist version in offline mode
5. **Better UI error messages** (configs.html)
- 404 shows "Не загружен" instead of "Ошибка загрузки"
- Network errors show "Не доступен" in gray
- Distinguishes between missing data and real errors
**Performance:**
- Before: 75s timeout on every offline request
- After: <5ms response time in offline mode
- Cached error state prevents repeated connection attempts
**User Impact:**
- UI no longer freezes when loading pages offline
- Instant page loads and API responses
- Pricelist version displays correctly in offline mode
- Clear visual feedback for offline state
Fixes Phase 2.5 offline mode performance issues.

- Added CountErroredChanges() method to count only pending changes with LastError
- Previously, error count included all pending changes, not just failed ones
- Added /api/sync/info endpoint with proper error count and error list
- Added sync info modal to display sync status, error count, and error details
- Made sync status indicators clickable to open the modal
- Fixed disconnect between "Error count: 4" and "No errors" in the list
