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.

## 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.

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

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.
