+Tests for BATON-ARCH-013: Keep-alive mechanism / health endpoint.
+
+Acceptance criteria:
+1. GET /health returns HTTP 200 OK.
+2. Response body contains JSON with {"status": "ok"}.
+3. Endpoint does not require authorization (no token, no secret header needed).
+4. Keep-alive loop is started when APP_URL is set, and NOT started when APP_URL is unset.
