Enhance bridge operation handling and improve JSON conversion

- Added new bridge operations to the bridgeOperationToString and bridgeOperationFromString functions for better command recognition.
- Implemented a fromCjson function to convert cJSON objects to DaliValue, supporting various data types including arrays and objects.
- Introduced isKnownBridgeRequestKey function to filter out unknown keys in bridge requests.
- Refactored handleDownlink to utilize the new fromCjson function for value and metadata extraction, improving code clarity and maintainability.
- Updated response creation to use a more structured approach with DaliValue's toJson method.
