vh 981ae4e6a1 feat(omnivoice): expose full generation surface (voice-design, language, diffusion params)
Wrapper /v1/audio/speech now accepts OmniVoice's whole surface:
- voice (clone, now OPTIONAL) and/or instruct (voice DESIGN). instruct is a CONTROLLED
  vocabulary (gender/age/pitch/accent/whisper tags, comma-separated), not free prose —
  discoverable at the new /v1/audio/instruct-items endpoint (23 items).
- language (Auto + 647, new /v1/audio/languages endpoint), speed, duration.
- diffusion controls: num_step, guidance_scale, denoise, preprocess_prompt,
  postprocess_output; plus a generation_overrides JSON passthrough for expert
  GenerationConfig knobs (t_shift, layer_penalty_factor, position/class temperature,
  audio_chunk_*).
- at least one of voice/instruct required (else 400).

Catalog (services.yaml): omnivoice v1 -> v2, 13 schema-valid fields; instruct as a
controlled-vocab text field sourced from the items endpoint.

Verified live on irv-ml1: clone, voice-design (instruct-only), and tuned-param synths
all -> 24 kHz PCM_16 WAV; 647 languages; 23 instruct items.
