Add comprehensive authentication system tests

- Introduced a new test script `test_auth.py` to verify the authentication system setup.
- Implemented tests for module imports, required environment variables, and FastAPI app creation.
- Added detailed output for each test to facilitate debugging and ensure all components are functioning correctly.
- The script serves as a foundational tool for validating the authentication system's readiness.
