fix(test): [1.1] Fix port conflict in TestOAuth

- Added --port=0 parameter to all TestOAuth test cases to avoid port conflicts
- This ensures tests use random available ports instead of fixed port 7070
- Resolves CI/CD test failures caused by port binding conflicts

Task: 1.1 - Fix TestOAuth port conflict issue
Phase: Testing
