fix: Resolve test isolation bug in pairing integration tests

- Drop persistence assertion in test_policy_allow_auto_approves to match production contract
- Add pytest.skipif decorator for test_real_agentic_flow_with_stub_adapter when OPENAI_API_KEY not available
- Fix contract mismatch where 'allow' policy returns True without persistent pairing
- Ensure tests either pass or skip gracefully without API key dependency
