**Windows compatibility:**
- Added filepath.Join for all template and static paths
- Fixes "path not found" errors on Windows
**Localhost binding:**
- Changed default host from 0.0.0.0 to 127.0.0.1
- Browser always opens on 127.0.0.1 (localhost)

- Updated config.example.yaml with comment about 0.0.0.0
This ensures the app works correctly on Windows and opens
browser on the correct localhost address.

This merge brings Phase 2.5 (Full Offline Mode) with the following improvements:
- Local-first architecture: all operations work through SQLite
- Background sync worker for automatic synchronization
- Sync queue (pending_changes table) for reliable data push
- LocalConfigurationService for offline-capable CRUD operations
- Pre-create pricelist check before configuration creation
- RefreshPrices works in offline mode using local_components
- UI improvements: sync status indicator, pricelist badge, unified admin tabs
- Fixed online mode: automatic MariaDB connection on startup
- Fixed nil pointer dereference in PricingHandler alert methods
- Improved setup flow with restart requirement notification
Phase 2.5 is now complete. Ready for production.
- 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.

**Changes:**
1. **Admin menu always visible** (base.html)
- Removed 'hidden' class from "Администратор цен" link
- Menu no longer depends on write permission check
- Users can access pricing/pricelists pages in offline mode
2. **Online status checks for mutations** (admin_pricing.html)
- Added checkOnlineStatus() helper function
- createPricelist() checks online before creating
- deletePricelist() checks online before deleting
- Clear user feedback when operations blocked offline
**User Impact:**
- Admin menu accessible in both online and offline modes
- View-only access to pricelists when offline

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.

Root cause: admin_pricing.html declared 'const showToast' while base.html
already defined 'function showToast', causing SyntaxError that prevented
all JavaScript from executing on the admin pricing page.
Changes:
- Removed duplicate showToast declaration from admin_pricing.html (lines 206-210)
- Removed debug logging added in previous commit
- Kept immediate function calls in base.html to ensure early initialization
This fixes the issue where username and "Администратор цен" link
disappeared when navigating to /admin/pricing.

- Added immediate calls to checkDbStatus() and checkWritePermission() in base.html
- Calls happen right after function definitions, before DOMContentLoaded
- Added console.log statements to track function execution and API responses
- Removed duplicate calls from admin_pricing.html to avoid conflicts
- This will help diagnose why username and admin link disappear on admin pricing page

- Parse URLSearchParams to detect ?tab=pricelists on page load
- Load tab from URL or default to 'alerts'
- Fixes redirect from /pricelists to /admin/pricing?tab=pricelists
This resolves the critical UX issue where users redirected from
/pricelists would see the 'alerts' tab instead of 'pricelists'.

- Pass originalHTML through syncAction function chain
- Simplify finally block by restoring original button innerHTML
- Remove hardcoded button HTML values (5 lines reduction)
