- Fix nil pointer dereference in PricingHandler alert methods
- Add automatic MariaDB connection on startup if settings exist
- Update setupRouter to accept mariaDB as parameter
- Fix offline mode checks: use h.db instead of h.alertService
- Update setup handler to show restart required message
- Add warning status support in setup.html UI
This ensures that after saving connection settings, the application
works correctly in online mode after restart. All repositories are
properly initialized with MariaDB connection on startup.

**Problem:**
Pricelist page showed empty list in offline mode even though
local pricelists existed in SQLite cache.
**Solution:**
Modified PricelistHandler.List() to fallback to local pricelists:
1. Check if server list is empty (offline)
2. Load from localDB.GetLocalPricelists()
3. Convert LocalPricelist to summary format
4. Add "synced_from": "local" field
5. Add "offline": true flag
**Response format:**
```json
{
"offline": true,
"total": 4,
"pricelists": [
{
"version": "2026-02-02-002",
"created_by": "sync",
"synced_from": "local",
"is_active": true
}
]
}
```
**Impact:**
- ✅ Local pricelists visible in offline mode
- ✅ UI can show cached pricelist versions
- ✅ Users can browse pricelists without connection
- ✅ Clear indication of local/remote source

**Problem:**
Configurator was broken in offline mode - no component search
and no price calculation because /api/components returned empty list.
**Solution:**
Added local component fallback to ComponentHandler:
1. **ComponentHandler with localDB** (component.go)
- Added localDB parameter to NewComponentHandler
- List() now fallbacks to local_components when offline
- Converts LocalComponent to ComponentView format
- Preserves prices from local cache
2. **Updated initialization** (main.go)
- Pass localDB to NewComponentHandler
**Impact:**
- ✅ Component search works offline
- ✅ Prices load from local_components table
- ✅ Configuration creation fully functional offline
- ✅ Price calculation works with cached prices
**Testing:**
- Verified /api/components returns local components
- Verified current_price field populated from cache
- Search, filtering, and pagination work correctly
Fixes critical Phase 2.5 offline mode issue.

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.

Updated sync-related code to use ConnectionManager instead of direct
database references:
- SyncService now creates repositories on-demand when connection available
- SyncHandler uses ConnectionManager for lazy DB access
- Added ComponentFilter and ListComponents to localdb for offline queries
- All sync operations check connection status before attempting MariaDB access
This completes the transition to offline-first architecture where all
database access goes through ConnectionManager.
Part of Phase 2.5: Full Offline Mode
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Introduced ConnectionManager to support offline-first architecture:
- New internal/db/connection.go with thread-safe connection management
- Lazy connection establishment (5s timeout, 10s cooldown)
- Automatic ping caching (30s interval) to avoid excessive checks
- Updated middleware/offline.go to use ConnectionManager.IsOnline()
- Updated sync/worker.go to use ConnectionManager instead of direct DB
This enables the application to start without MariaDB and gracefully
handle offline/online transitions.
Part of Phase 2.5: Full Offline Mode
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Fixed two critical issues preventing offline-first operation:
1. **Instant startup** - Removed blocking GetDB() call during server
initialization. Server now starts in <10ms instead of 1+ minute.
- Changed setupRouter() to use lazy DB connection via ConnectionManager
- mariaDB connection is now nil on startup, established only when needed
- Fixes timeout issues when MariaDB is unreachable
2. **Offline mode nil pointer panics** - Added graceful degradation
when database is offline:
- ComponentService.GetCategories() returns DefaultCategories if repo is nil
- ComponentService.List/GetByLotName checks for nil repo
- PricelistService methods return empty/error responses in offline mode
- All methods properly handle nil repositories
**Before**: Server startup took 1min+ and crashed with nil pointer panic
when trying to load /configurator page offline.
**After**: Server starts instantly and serves pages in offline mode using
DefaultCategories and SQLite data.
