fix: resolve pytest failures by adding missing dependencies and fixing async tests

- Add pytest and pytest-asyncio to requirements.txt for proper async testing
- Fix async test functions to properly handle await and mocking
- Correct function signatures and parameters in detect_waf and detect_proxy tests
- Fix SSL certificate test mocking with proper datetime and version attributes
- Update mocking strategies for better test isolation
- Ensure all 5 tests pass: port scanning, SSL info, HTTP headers, WAF detection, and full proxy analysis
