Fix siren advanced controls

[karwosts]

Proposed change

According to demo siren and developer docs:

• volume should be volume_level
• available_tones can be an array or a dict. The current code is only correctly handling dicts (I think, I don't have one). The demo siren uses an array, so this code fixes the dialog for the demo siren, I think it should work for arrays or dicts.
