fix(GRO-1544): restore /health alongside /api/health endpoint

The previous GRO-1544 PR changed /health to /api/health but removed
the /health endpoint entirely. This breaks:
- Dockerfile HEALTHCHECK (curl -f http://localhost:3000/health)
- K8s readinessProbe/livenessProbe (httpGet: path: /health, port: 3000)

Both paths are registered before auth middleware so both remain
publicly accessible without authentication.
