Fix multiserver deployment: domain in docker-provider and auto-disable remote Traefik

- Fix missing domain in docker provider defaultRule (use DOMAIN or DUCKDNS_DOMAIN)
- Add disable_traefik_on_remote_services() to strip routing labels from remote services
- Call disable function automatically during remote server deployment (Step 5.5)
- Remote services now properly accessed through core Traefik via docker provider
- Prevents errors: middleware/certresolver not found on remote Traefik

Resolves Traefik errors on remote servers where services had labels for
SSL/auth that only exist on core server.
