Moves the audio-context/Pizzicato setup, TTS fetch+playback pipeline,
controller/readback speech scheduling, and the radio-check handling
(RADIO_CHECK_RE/SAY_AGAIN_RE/FAREWELL_RE, answerRadioCheck,
performRadioCheck, readability quick-select) out of live-atc.vue.
The interrupt primitives (stopCurrentSpeech/enqueueSpeech and the
audio/abort bookkeeping they tear down) live in a separate
useSpeechInterrupt because useFrequencyPresets needs stopCurrentSpeech
while useRadioSpeech needs frequency state — one composable owning both
would be circular. useSpeechInterrupt is constructed first and threaded
into both.
signalStrength/speechSpeed/radioCheckLoading/radioEffectsEnabled/
readbackEnabled stay page-level refs and are passed in, because
useAtisPlayback already consumes signalStrength before useRadioSpeech
can be constructed (it needs handlePilotTransmission).
