Add button no longer displayed
### Describe The Bug

### What is happening?

The "Add" button for the homebridge-dummy plugin has disappeared:

<img width="812" alt="Image" src="https://github.com/user-attachments/assets/e5159a9f-8baa-45ec-a1a9-3ea6af54d048" /><p>

### What you expect to happen?

The last version of homebridge-dummy was published 2 years ago, so this is not a change in the plugin. This must have been a change to the UI.

Also, the individual switches in homebridge-dummy could be dragged and reordered. That functionality has disappeared also.
