Bind navidrome, n8n, immich, openclaw, gitea web ports to 127.0.0.1
to prevent direct LAN access bypassing Caddy/Authelia.
Tailscale userspace networking on Synology proxies through localhost,
so VPS Caddy access via Tailscale IP continues to work.
Gitea SSH port (2222) remains on all interfaces for external git push.
Phase 6: OpenClaw docker-compose (port 3100) with health check
Phase 9: Enhanced backup.sh with full DB/config coverage + Telegram alerts
Phase 10: Health checks on all compose files, /api/system/notify endpoint
