http: api: smoketests fail as they can not establish IPv6 connection to uvicorn backend server
Closed, ResolvedPublicBUG

Description added a bunch of new smoketests.

While debugging those failing, it was uncovered, that uvicorn only listens on IPv4 connections

As the CLI already has an option to move the API communication from an IP socket to a UNIX domain socket, the best idea is to make this the default way of communication, as we never directly talk to the API server but rather use the NGINX reverse proxy.

Migrate the CLI to and always use the socket CLI option
Rename listen-port from virtual-host to port to be consistent with other CLI components
