reproduce ganador en dispositivo seleccionado si lo permite

- play_winner acepta device_id del formulario y verifica que el
  dispositivo exista y no sea restringido antes de reproducir
- corrige construcción del URI según spotify_type del ganador
  (antes siempre usaba spotify:playlist: independiente del tipo)
- errores se muestran en la página admin en lugar de HTTPException cruda
- template sincroniza device_id activo al campo oculto del formulario
- dispositivos restringidos se marcan en el selector del admin
