🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle the permanently denied RECORD_AUDIO case.

If the user permanently denies RECORD_AUDIO, micPermissionLauncher.launch(...) returns denied without showing a dialog. The switch then stays off and the user gets no explanation. Add feedback for this state, for example a message that points to the app settings, and track whether the request was already made so first run is still distinguished from permanent denial.

Based on learnings, permission logic should combine checkSelfPermission with shouldShowRequestPermissionRationale and a persisted "has requested before" flag to separate first run, rationale needed, and permanently denied states.

lines 363 - 366, Update the microphone permission flow around
micPermissionLauncher and the enabled switch to track a persisted “has requested
before” state, combine checkSelfPermission with
shouldShowRequestPermissionRationale, and distinguish first request,
rationale-needed, and permanently denied RECORD_AUDIO cases. After a prior
request is permanently denied, keep the switch off and provide feedback
directing the user to app settings; preserve the normal launcher request on the
initial request.
