cms: headless CMS vor Hugo (Supabase + Node-API + React-Admin)

All-in-One docker-compose-Stack (Muster von RAPPORT-SERVER gespiegelt):
db/auth/rest/kong + cms-Service (Node-API + Hugo-Binary 0.161.1 + Admin-SPA).

- DB-backed: posts-Tabelle kanonisch, MD ist generiertes Artefakt
- echte Hugo-Vorschau via draft:true + --buildDrafts → /_preview
- Publish: DB → content/library/<section>/<slug>.md → hugo build → live
- Bild-Upload nach static/images/, Supabase-Auth schützt /api/*
- Proxmox-LXC-Script: legt Container an, generiert Secrets, startet Stack
