feat: Music Assistant, Claude primary LLM, model tag in chat, setup.sh rewrite

- Deploy Music Assistant on Pi (10.0.0.199:8095) with host networking for
  Chromecast mDNS discovery, Spotify + SMB library support
- Switch primary LLM from Ollama to Claude Sonnet 4 (Anthropic API),
  local models remain as fallback
- Add model info tag under each assistant message in dashboard chat,
  persisted in conversation JSON
- Rewrite homeai-agent/setup.sh: loads .env, injects API keys into plists,
  symlinks plists to ~/Library/LaunchAgents/, smoke tests services
- Update install_service() in common.sh to use symlinks instead of copies
- Open UFW ports on Pi for Music Assistant (8095, 8097, 8927)
- Add ANTHROPIC_API_KEY to openclaw + bridge launchd plists
