[WEB-5575]feat: enhance APITokenLogMiddleware to support logging to MongoDB (#8241)

* feat: enhance APITokenLogMiddleware to support logging to MongoDB

- Added functionality to log external API requests to MongoDB, with a fallback to PostgreSQL if MongoDB is unavailable.
- Implemented error handling for MongoDB connection and logging operations.
- Introduced additional fields for MongoDB logs, including timestamps and user identifiers.
- Refactored request logging logic to streamline the process and improve maintainability.

* fix: improve MongoDB availability checks in APITokenLogMiddleware

- Enhanced the logic for determining MongoDB availability by checking if the collection is not None.
- Added a check for MongoDB configuration before attempting to retrieve the collection.
- Updated error handling to ensure the middleware correctly reflects the state of MongoDB connectivity.

* feat: implement logging functionality in logger_task for API activity

- Added a new logger_task module to handle logging of API activity to MongoDB and PostgreSQL.
- Introduced functions for safely decoding request/response bodies and processing logs based on MongoDB availability.
- Refactored APITokenLogMiddleware to utilize the new logging functions, improving code organization and maintainability.

* refactor: simplify MongoDB logging in logger_task and middleware

- Removed direct dependency on MongoDB collection in log_to_mongo function, now retrieving it internally.
- Updated process_logs to check MongoDB configuration before logging, enhancing error handling.
- Cleaned up logger.py by removing unused imports related to MongoDB.

* feat: add Celery task decorator to process_logs function in logger_task

- Introduced the @shared_task decorator to the process_logs function, enabling asynchronous processing of log data.
- Updated function signature to include a return type of None for clarity.
