Wires one Media-Streams socket: authenticate + bind on start, dispatch inbound frames, tear down on close.
A socket whose start frame names an unknown call, carries a bad/missing mjToken, or targets a call that
already has a socket is closed and logged — and its later close does NOT end the (legitimate) call.
A socket that never sends a valid start within MEDIA_SOCKET_AUTH_DEADLINE_MS is closed and logged.
