Replaced raw database queries with CRUD operations for consistency and modularity. Enhanced error handling by adding detailed exception messages and logging for failed actions, such as authentication and registration. Updated tests to reflect new exception-based error handling approach.
Moved `auth` module from `dependencies.py` to `dependencies/auth.py` for better organization. Added extensive unit tests for authentication services and API dependencies to ensure robust verification of users, tokens, and permissions.
Eliminated the `RevokedToken` model and associated logic for managing token revocation. Removed unused files, related tests, and outdated dependencies in authentication modules. Simplified token decoding, user validation, and dependency injection by streamlining the flow and enhancing maintainability.
