Fix mic icon color for radio

[Sharkiiie]

Previously: The mic icon would be white when not speaking, yellow when speaking in proximity, and red when speaking in prox or over radio when radio is on.

Now: White when not speaking, yellow when speaking in prox, and red when speaking over the radio.

Small change, but this has bugged me for months lmao Seems to be the intended behavior anyway
