Subject: [PATCH] fix(kokoros): implement AudioTranscriptionLive trait stub
 (#10612)

The backend.proto AudioTranscriptionLive bidirectional streaming RPC added
new required trait items (AudioTranscriptionLiveStream + audio_transcription_live)
on the generated Backend trait. The kokoros (TTS) backend did not implement
them, breaking its release build with E0046 (missing trait items).

kokoros is text-to-speech and has no live-ASR support, so stub the method to
return UNIMPLEMENTED, mirroring the existing audio_transcription_stream stub.
