-Tests for BATON-FIX-007: CORS OPTIONS preflight verification.
-
-Acceptance criteria:
-1. OPTIONS preflight to /api/signal returns 200.
-2. Preflight response includes Access-Control-Allow-Methods containing GET.
-3. Preflight response includes Access-Control-Allow-Origin matching the configured origin.
-4. Preflight response includes Access-Control-Allow-Headers with Authorization.
-5. allow_methods in CORSMiddleware configuration explicitly contains GET.
