Add background sync worker and complete local-first architecture

Implements automatic background synchronization every 5 minutes: - Worker pushes pending changes to server (PushPendingChanges) - Worker pulls new pricelists (SyncPricelistsIfNeeded) - Graceful shutdown with context cancellation - Automatic online/offline detection via DB ping New files: - internal/services/sync/worker.go - Background sync worker - internal/services/local_configuration.go - Local-first CRUD - internal/localdb/converters.go - MariaDB ↔ SQLite converters Extended sync infrastructure: - Pending changes queue (pending_changes table) - Push/pull sync endpoints (/api/sync/push, /pending) - ConfigurationGetter interface for handler compatibility - LocalConfigurationService replaces ConfigurationService All configuration operations now run through SQLite with automatic background sync to MariaDB when online. Phase 2.5 nearly complete. Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
