Liveness check

GET 
/health/live

Returns 200 as long as the HTTP server thread can respond. Use this for Kubernetes liveness probes to determine whether to restart a pod. This endpoint is exempt from authentication so probes can reach it without credentials. A root-level alias at /health/live (outside the /api base path) is also available for GTMs that require probes at well-known root paths.
