Add Wyoming voice stack to pyinfra + landscape doc

- Move piper-compose.yaml / whisper-compose.yaml from repo root into
  pyinfra/framework/compose/{piper,whisper}.yml; bind paths shifted to
  /srv/docker/{piper,whisper}/data on the box.
- deploy.py registers both stacks and provisions the data dirs.
- Homepage gets a "Voice" group with informational tiles (Wyoming has
  no web UI, so tiles show container status without click-through).
- New VoiceModels.md captures the May 2026 STT/TTS landscape, why the
  current Wyoming defaults aren't SOTA, and concrete upgrade paths
  (whisper-large-v3-turbo + faster-whisper-server, Kokoro, Sesame CSM,
  F5-TTS for cloning).
