- CORS config is now actually applied to the router (the middleware
existed but was never wired); preflight returns 204 for allowed
origins and 403 with no CORS headers for disallowed ones.
- /readyz runs real dependency checks (queue, auth database) and
returns 503 with per-component detail when not ready; exported
handlers support dedicated health listeners.
- Optional server.tls (cert_file/key_file) for REST and gRPC, validated
at config load.
- 5xx responses no longer echo internal error details; not-found and
already-sent map to 404/409 on cancel/retry.
