Eturnal Signaling server App

I think the “eturnal1” is the right HTTP route that has the correct hostname but in this case it’s not important as it’s not a webapp.

@oneitonitram there are still 2 ports configured for traefik in ../actions/configure-module/20configure_traefik, I think they are not needed.

I don’t get why it complains about ports already in use but the ports are not shown with the ss command.
