Enhance logging and error handling in E2E tests and CI workflows

- Added detailed log messages in `conftest.py` for SSL certificate and JWT generation steps.
- Improved Docker Compose E2E test output with service-specific logs during startup and cleanup.
- Adjusted pytest run options in CI workflows to use `--tb=short` for concise error traceback.
