feat: web-client — синхронизация команд с satellite

Изменения:
- Перенесён start_server.py в web-client/
- Обновлены команды в client.html для соответствия satellite
- handle_websocket_command поддерживает:
  - set_volume (level/volume)
  - mute/unmute
  - play_sound
  - set_led_brightness
  - trigger_event
- Обновлён обработчик входящих событий:
  - voice-started/voice-stopped
  - transcript
  - synthesize
  - audio-start/audio-stop/played
  - timer-started/timer-finished
  - streaming-started/streaming-stopped
  - satellite-connected/satellite-disconnected
  - error
  - audio-level (RMS)

Теперь client.html полностью соответствует API satellite
