* feat(voice): allow selecting a microphone for dictation
Persist a preferred audioinput device in Voice settings and pass it into
getUserMedia, falling back to the system default when the device is gone.
* fix(voice): resolve mic preference by label and detect mid-capture loss
Drop Chromium's 'default'/'communications' aliases from the picker — pinning
one behaved exactly like system default and silently defeated the setting.
Resolve a stored preference against the live device list before capturing:
a unique label match heals an id that Chromium re-salted, a known-missing
device skips the doomed getUserMedia attempt that clipped the first words,
and an unreadable list no longer reads as "unplugged".
Surface the input ending mid-dictation instead of feeding silent zeros, add
a permission affordance so the picker is not empty before mic access, and
toast the fallback once per preference rather than once per utterance.
