Adds the production cluster foundation (authored + applied live on node1): - cert-manager via the k3s HelmChart controller + letsencrypt staging/prod ClusterIssuers (HTTP-01 / Traefik). - Longhorn config for single-node (values: replica=1, default StorageClass, Retain) + backup-to-Hetzner-Object-Storage credential template. - In-cluster data tier (dezky-data): Postgres 16 (with Authentik+OCIS DB init), MongoDB 7, Redis 7 as StatefulSets on Longhorn, + secret template. - bootstrap.sh: install open-iscsi/nfs-common + enable iscsid (Longhorn prereq). - RUNBOOK.md: full reproducible node1 build order. Real secrets are generated on-box and kept in Bitwarden — never in git.
