doorman/scripts/test-shims

These are optional developer shims that used to live at the repo root.

• test_ip_filter_platform.py and test_platform_expanded.py allow running select backend tests via their shim paths.
• conftest.py mirrors backend test fixtures for the shims.
• sitecustomize.py mirrors logging redaction behavior for ad-hoc runs; primary copies exist under backend-services/ and backend-services/tests/.

They are not required for normal test execution. Use make unit or run pytest from backend-services/.
