fix(icom): the console PTT carries the microphone on a network station

Keying alone is right on USB, where the operator talks into the radio's own
mic; over the LAN it transmitted silence. The console button now goes through
one binding that picks the road: network To-radio → the same key-and-stream
path as the Talk button, USB → key and nothing more.
