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>
