## Overview
Removed the CurrentPrice and SyncedAt fields from local_components, transitioning to a
pricelist-based pricing model where all prices are sourced from local_pricelist_items
based on the configuration's selected pricelist.
## Changes
### Data Model Updates
- **LocalComponent**: Now stores only metadata (LotName, LotDescription, Category, Model)
- Removed: CurrentPrice, SyncedAt (both redundant)
- Pricing is now exclusively sourced from local_pricelist_items
- **LocalConfiguration**: Added pricelist selection fields
- Added: WarehousePricelistID, CompetitorPricelistID
- These complement the existing PricelistID (Estimate)
### Migrations
- Added migration "drop_component_unused_fields" to remove CurrentPrice and SyncedAt columns
- Added migration "add_warehouse_competitor_pricelists" to add new pricelist fields
### Component Sync
- Removed current_price from MariaDB query
- Removed CurrentPrice assignment in component creation
- SyncComponentPrices now exclusively updates based on pricelist_items via quote calculation
### Quote Calculation
- Added PricelistID field to QuoteRequest
- Updated local-first path to use pricelist_items instead of component.CurrentPrice
- Falls back to latest estimate pricelist if PricelistID not specified
- Maintains offline-first behavior: local queries work without MariaDB
### Configuration Refresh
- Removed fallback on component.CurrentPrice
- Prices are only refreshed from local_pricelist_items
- If price not found in pricelist, original price is preserved
### API Changes
- Removed CurrentPrice from ComponentView
- Components API no longer returns pricing information
- Pricing is accessed via QuoteService or PricelistService
### Code Cleanup
- Removed UpdateComponentPricesFromPricelist() method
- Removed EnsureComponentPricesFromPricelists() method
- Updated UnifiedRepository to remove offline pricing logic
- Updated converters to remove CurrentPrice mapping
## Architecture Impact
- Components = metadata store only
- Prices = managed by pricelist system
- Quote calculation = owns all pricing logic
- Local-first behavior preserved: SQLite queries work offline, no MariaDB dependency
## Testing
- Build successful
- All code compiles without errors
- Ready for migration testing with existing databases

Sync was blocked because the migration registry table creation required
CREATE TABLE permissions that the database user might not have.
Changes:
- Check if migration registry tables exist before attempting to create them
- Skip creation if table exists and user lacks CREATE permissions
- Use information_schema to reliably check table existence
- Apply same fix to user sync status table creation
- Gracefully handle ALTER TABLE failures for backward compatibility
This allows sync to proceed even if the client is a read-limited database user,
as long as the required tables have already been created by an administrator.

- Move data-description from SVG to button element for reliable access
- Add disabled guard on bulk add/ignore buttons to prevent duplicate requests
- Return explicit error in UpsertIgnoreRule when rule already exists

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.

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.

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.
