Feature request — combined audio OSD (device name + volume slider)

Currently VolumeOSD and AudioOutputOSD are two separate popups. When the audio output device changes, both can fire and briefly stack on top of each other.

Would it be possible to add an optional device-name line to VolumeOSD (sourced from AudioService.displayName() of the current sink), so a single popup shows the icon, the device name, and the volume slider together? This would be especially useful for setups using custom device aliases, where the alias is the whole point of having the name visible.

Happy to provide more detail or a sketch of the change if that's useful.

Locate the VolumeOSD and AudioOutputOSD entry points and inspect how AudioService.displayName() provides the current sink name. Confirm how the two popups are triggered, then make the device-name line optional in VolumeOSD so the combined popup shows the icon, name, and slider without stacking; verify both enabled and disabled behavior.
