Previously /api/health did deep dependency probes (postgres + redis +
minio) and 503'd on any failure. That's readiness behavior, not
liveness — a transient Redis/MinIO blip would tell the orchestrator to
restart the pod when it should only be dropped from the load balancer.
Make /api/health a thin liveness check (returns 200 unconditionally if
the process is responding) and move the deep checks to a new
/api/ready endpoint with the canonical Kubernetes-style 200/503
contract. Docker-compose healthchecks keep pointing at /api/health,
which is now more conservative (no false-positive container restarts).
Documenso/SMTP are intentionally not probed in /api/ready: each tenant
configures its own credentials and a tenant misconfiguration shouldn't
deadline the entire shared CRM.
Also tighten the gdpr-bundle-builder casts: replace the scattered
`as unknown as Record<string, unknown>` double-casts with a small
`toJsonRow<T>()` helper that does the widen narrow→wide in one place
with one cast hop instead of two.
