Add OpenAI-compatible voice servers (faster-whisper + Kokoro)

Path B from VoiceModels.md — adds two new compose stacks alongside the
Wyoming pair so OpenWebUI/Conduit get voice without a Wyoming-shim:

- compose/faster-whisper.yml — fedirz/faster-whisper-server CPU image,
  large-v3-turbo by default, OpenAI /v1/audio/transcriptions on :8001.
  Built-in web UI for ad-hoc transcription.
- compose/kokoro.yml — ghcr.io/remsky/kokoro-fastapi-cpu, Kokoro-82M,
  OpenAI /v1/audio/speech on :8880.

Both run alongside (not instead of) Wyoming Whisper + Piper — Wyoming
keeps serving HA Assist, OpenAI-API serves OpenWebUI / Conduit. Memory
budget on Strix Halo accommodates everything plus Qwen3-Coder loaded
concurrently with plenty of headroom.

Homepage gets dedicated tiles for both. README documents the
OpenWebUI Audio configuration that wires the new endpoints. Conduit
inherits voice via OpenWebUI without app-side setup.
