Refactor geocoding services and improve logging

- Updated the Nominatim geocoding service to use a class-based structure and accept a logger instance for better logging control.
- Modified tests for the Nominatim service to align with the new structure and improved logging assertions.
- Removed the disabled notification service test file.
- Added a new GeocodingFailedError class to handle geocoding failures more explicitly.
- Enhanced error logging in the queue service to include structured error objects.
- Updated user service to accept a logger instance for better logging in address upsert operations.
- Added request-scoped logger to Express Request interface for type-safe logging in route handlers.
- Improved logging in utility functions for better debugging and error tracking.
- Created a new GoogleGeocodingService class for Google Maps geocoding with structured logging.
- Added tests for the useAiAnalysis hook to ensure proper functionality and error handling.
