Refactor logging and improve service initialization

- Updated logging in `search-server.ts` to use `silentDebug` for non-critical messages, reducing console noise.
- Added a health check endpoint in `worker-service.ts` to improve service monitoring.
- Modified the worker service startup process to start the HTTP server immediately and perform slow initialization in the background.
- Refactored database initialization in `Database.ts` to use the correct `Database` class.
- Implemented a port availability check in `context-hook.ts` to ensure the worker service is ready before making requests.
