Add link analysis tests and integration tests for /links/analyze endpoint

- Implemented `test_link_analysis` in `test_docker.py` to validate link analysis functionality.
- Created `test_link_analysis.py` with comprehensive tests for link analysis, including basic functionality, configuration options, error handling, performance, and edge cases.
- Added integration tests in `test_link_analysis_integration.py` to verify the /links/analyze endpoint, including health checks, authentication, and error handling.
