refactor: improve logging factories and extend test coverage

- Refactored LoggerProcessorFactory and LoggerHandlerFactory to handle missing or empty processor/handler configurations gracefully without throwing exceptions.
- Enhanced configurability and flexibility by improving initialization methods for logging components.
- Added new unit tests for QueryLogger, MetricsProcessor, AnonymizerProcessor, and EncryptionProcessor, increasing overall test coverage.
- Removed obsolete LoggerHandlerFactory test under Formatter namespace.
- Updated mock expectations and assertions in existing tests for handlers and processors to ensure accurate and consistent behavior.
- Cleaned up unnecessary dependencies and ensured better isolation in test cases.
