Support binding to sockets again

[karlbeecken]

Describe the enhancement

The old dashboard used to support binding the webserver to a socket instead of a port. device-builder is missing this feature, I would like to have this feature again in device-builder.

I would be happy to submit a PR for this, as it shouldn't be that big of a change, aiohttp already supports binding to sockets anyway.

Use cases

Bind the webserver to a socket for more granular permissions and less waste of ports.
