network_backend: use resolved device name in console output

NetworkBackend's connect/send/lost/error prints always used the
connect-time registration name, so GUI console output kept showing
the placeholder counter ID even after MON-VER resolved the real
device name. Add a display_name per socket (defaults to name, kept
separate from the routing key used by find_by_name/register_xcvr) and
have the GUI update it once MON-VER responds.
