fix: resolve quality gate failures for PR 8

- Remove pytest timeout flags causing CI failures
- Add missing aiohttp dependency for async operations
- Fix security vulnerability in hashlib.md5 usage with usedforsecurity=False
- Fix FastAPI TestClient configuration for router testing
- Remove parallel testing configuration causing instability

These changes address the critical quality gate failures preventing CI from passing.
