Add option the toggle ethernet in the popup

### Feature Description

Currently we can toggle Wi-Fi but can't toggle ethernet, so adding a toggle there would be nice.

### Use Case

When you want to disconnect and reconnect Ethernet we should be able to toggle the ethernet option in the popup of Dankbar

### Compositor(s)

All compositors

### If Other, please specify

### Proposed Solution

### Alternatives/Existing Solutions

_No response_

Start by locating the existing Wi-Fi toggle implementation in Dankbar's popup and trace how it changes connection state. Add equivalent Ethernet behavior and verify that disconnecting and reconnecting Ethernet works in the popup across all compositors.
