fix: revert to runs-on: ubuntu-latest (the working configuration)

The runner was always configured with ubuntu-latest label, not nas.
Using ubuntu-latest with Docker-in-Docker works because runner has
/volume1/docker/nas-dashboard in valid_volumes.

Also keep the network creation fix to prevent duplicates.
