- Add a NAS-specific frpc template that forwards to tuwen_web:80 over the compose network.
- Make docker-compose-Nas.yaml create tuwen_frpc by default instead of relying on Compose profiles, which Container Station may not enable.
- Remove host networking from the NAS frpc service so the tunnel works through Docker service DNS.
- Update README and Docker docs to explain the NAS frpc behavior and logs command.
