feat(pss): drop 5 namespaces from PSS privileged to restricted
argocd, cert-manager, cloudnative-pg already compliant — label flip only.
ocis: add overlay injecting seccompProfile=RuntimeDefault, drop ALL caps,
allowPrivilegeEscalation=false across all chart Deployments/CronJobs;
patch idm initContainer; harden custom precheck Job; refactor s3-backup
to rclone/rclone image (avoids apk-add-as-root).
victoria-metrics-single: overlay sets full restricted SC on the StatefulSet
that ships with empty securityContext: {}.
forgejo, traefik, kube-system stay privileged (hostPort / CSI driver).
