Michael Chus	c024b96de7	fix: enable instant startup and offline mode for server ... 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.

Michael Chus	143d217397	Add Phase 2: Local SQLite database with sync functionality ... Implements complete offline-first architecture with SQLite caching and MariaDB synchronization. Key features: - Local SQLite database for offline operation (data/quoteforge.db) - Connection settings with encrypted credentials - Component and pricelist caching with auto-sync - Sync API endpoints (/api/sync/status, /components, /pricelists, /all) - Real-time sync status indicator in UI with auto-refresh - Offline mode detection middleware - Migration tool for database initialization - Setup wizard for initial configuration New components: - internal/localdb: SQLite repository layer (components, pricelists, sync) - internal/services/sync: Synchronization service - internal/handlers/sync: Sync API handlers - internal/handlers/setup: Setup wizard handlers - internal/middleware/offline: Offline detection - cmd/migrate: Database migration tool UI improvements: - Setup page for database configuration - Sync status indicator with online/offline detection - Warning icons for pending synchronization - Auto-refresh every 30 seconds Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2026-02-01 11:00:32 +03:00
