Complete and fix boWave project: Resolve TopBar hook issue and finalize production readiness

Fixed critical issues:
- TopBar.jsx: Changed useState to useEffect for clock timer (was causing runtime error)
- Added .gitignore to exclude build artifacts and node_modules

Improvements and additions:
- Enhanced docker-compose configs for robust dev/boot modes
- Added Dockerfile.dev for dashboard and librespot
- Updated Makefile with all necessary targets
- Comprehensive README with troubleshooting guide
- All API clients with proper error handling and reconnection logic
- Mock system fully functional for dev mode
- All 4 dashboard pages complete with real-time data binding
- Audio pipeline: Spotify/AirPlay/Mopidy → Snapserver → Multiroom zones

Project is now fully functional and production-ready:
✓ Builds successfully (React 18 + Vite)
✓ Docker config valid for both dev and boot modes
✓ All components tested and working
✓ Error handling and graceful degradation implemented
✓ Touch-optimized UI with proper styling
✓ Hot reload enabled in dev mode
