feat: implement WorkProcessor and search execution services

- SearchRepository: Search table operations with Dapper - SearchExecutionService: Search pipeline with proper cancellation handling - WorkProcessor: Unified BackgroundService for syncs and searches - SearchNotificationService: SignalR notifications in Api layer All 45 new tests pass. Proper shutdown vs timeout distinction prevents marking searches as error on host shutdown.
