services: add standalone bootstrap to arm, authelia, backup, borg-backup, caddy, ntfy

Each service can now be run directly with sudo bash <service>.sh on any
machine with Docker installed, without needing the full post-install repo.
Uses the shared bootstrap pattern from docs/standalone-template.sh.
