Nextcloud: custom Dockerfile (nextcloud:apache + smbclient) for SMB external
storage support without AIO. All data uses bind mounts so Kopia/Borg coverage
is automatic. Enables files_external app after first boot.
OnlyOffice: JWT-secured document server wired to Nextcloud via occ commands
and FileBrowser Quantum config.yaml if both are installed. Port 8082.
Mattermost: Team Edition + PostgreSQL + dedicated coturn on port 3479 (does
not conflict with Easy Asterisk's coturn on 3478). Bind mounts throughout.
UFW rules and router port-forward instructions printed at install time.
