fix(ci): fix integration test collection and skip Playwright in CI

- Add @pytest.mark.oauth to OAuth-dependent tests in
  test_scope_authorization.py so they're excluded from single-user job
- Add module-level pytestmark to test_introspection_authorization.py
- Fix single-user marker expression to also exclude oauth smoke tests
- Add --ignore paths for multi-user, qdrant, and RAG evaluation tests
- Uncomment GITHUB_ACTIONS skip in oauth_callback_server fixture
- Add GITHUB_ACTIONS skip to login_flow_oauth_token fixture
- Mount third_party/oidc volume in docker-compose.yml app service
- Add OIDC diagnostic step in CI for playwright jobs
