Refactored the event API routes to improve error handling, add logging, and provide enhanced response structures with pagination. Updated tests to use new fixtures and include additional authentication utilities to facilitate testing with FastAPI's dependency injection. Also resolved issues with timezone awareness in event schemas.
Renamed `event_theme` and `test_user_schema` file paths and imports to follow consistent plural naming conventions. This improves code clarity and aligns file and import naming across the project.
Introduced CRUD implementation, schema definitions, and tests for EventTheme. This allows creation, retrieval, updating, deletion, and querying of active event themes. Comprehensive tests ensure functionality works as intended, including edge cases for nonexistent themes.
