Enhance REST API controller: GET params support and safe serialization 

- Added support for retrieving fields via query parameters in GET requests, in addition to JSON body.
- Improved response serialization, including:
  * Conversion of datetime/date to ISO format.
  * Conversion of binary fields to base64.
  * Safe handling of non-serializable iterables.
- Added error handling blocks with logging for better traceability.
- Simplified fields extraction logic in GET/POST/PUT.
- Preserved compatibility with api-key authentication and authorization logic.
