CronJobs referenced bare image 'myorg-assistant:latest' which cannot be
pulled, causing all scheduled jobs to sit in ImagePullBackOff.
Pin to the same image used by the Deployment.
The ingresses referenced a Cloudflare OriginIssuer 'prod-issuer' whose CRD
and controller are not installed in the cluster, so cert-manager could not
issue certs and Traefik served a default cert (invalid SSL). Switch to the
existing letsencrypt-prod ClusterIssuer with specific hostnames + per-app
secrets, matching the working ingresses (http-01 cannot issue wildcards).
