Refactor event API and extend authentication utilities

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.
