traefik-file-provider-required-for-non-docker-systemd-services

Systemd-managed services (like xint on port 18207) cannot use Docker label-based Traefik routing. They require a Traefik file-provider dynamic config in /root/dynamic/ with explicit entrypoints, rule, service, and loadBalancer.servers definitions. This is the correct pattern for any VPS service not running inside a Docker container.
