Add docker-compose.speech.yml with three speech services:
- Speaches (STT via Whisper + basic TTS) on port 8090
- Kokoro-FastAPI (default TTS) on port 8880
- Chatterbox TTS (premium, GPU-required) on port 8881 behind
the premium-tts profile
All services include health checks, connect to the mosaic-internal
network, and follow existing naming/labeling conventions. Makefile
targets added: speech-up, speech-down, speech-logs.
