POST /sendVoice
Voice messages accept OGG/Opus or convert=true hint.
Client UX should:
1.
record locally and offer playback,
2.
convert to acceptable format client-side when possible, or set convert=true
3.
and show conversion progress.
Validate file extension and mimetype early; otherwise surface bad_format guidance instructing the user to re-record or enable conversion.
For low-latency UX, upload and immediately show a “sending” waveform; update with success/failure.
