These migrated to ringtail. Set replicas: 0 (prevents resurrecting the old
instances and double-writing the now-ringtail-owned databases) and remove the
tailscale Ingress from each (the names tesla/meals/paperless were handed off
to the -ringtail ingresses at cutover; a re-created minikube ingress would
steal them back). Service/PVC/ExternalSecrets retained for rollback. Manifest
deletion + source-DB drop come in a later decommission PR.
