vh 06eb487a26 feat(omnivoice): wire to asset-engine via FastAPI wrapper + reuse chatterbox voices
- app.py: thin FastAPI wrapper exposing OpenAI /v1/audio/speech (+ /v1/audio/voices,
  /healthz) around OmniVoice's Python API; precomputes a voice-clone prompt per voice
  at startup (loaded Whisper auto-transcribes each reference). Replaces the Gradio demo.
- Dockerfile/compose: run the uvicorn wrapper, /healthz healthcheck, project name pinned
  to "omnivoice" so the asset-engine liveness probe matches.
- deploy-omnivoice.yaml: stage chatterbox /refs/*.wav as clone voices (skip _* artifacts)
  + verify the API surface.
- services.yaml: catalog entry (id omnivoice, :8199/v1/audio/speech, voice list sourced
  live from /v1/audio/voices) + reproducibility_audit row.

Verified live on irv-ml1: /healthz ok, 33 voices loaded, test synth -> 24kHz PCM_16 WAV.

# OmniVoice (k2-fsa/OmniVoice) — zero-shot, massively-multilingual (600+
# languages) voice-cloning + voice-design TTS, diffusion-LM architecture,
# Apache-2.0. Upstream ships a pip package + its own Gradio demo
# (`omnivoice-demo`); there's no official image, so we build a thin CUDA
# container around the pip package and run its Gradio server directly.
# Unlike index-tts we DON'T need a FastAPI wrapper — OmniVoice serves itself.
