feat(live-atc): squelch open/close transients around transmissions

Browse Source 
Carrier-open click at speech start, ~230ms noise tail cut off by a closing
click at speech end. Playback holds the effect chain alive past the voice so
the tail rings out instead of being killed with the noise generators.
