[Bug]: mark pipewire playback stream as "Idle" when wallpaper is muted

[Theslees]

I have:

• [ yes] Searched if this issue hasn't been reported yet.
• [yes ] Verified that I am using the latest version (Wallpaper settings > top right corner for version 1.0.0 and later), should be the same as https://github.com/luisbocanegra/plasma-smart-video-wallpaper-reborn/releases/latest

Install method used:

• [ yes] Using Plasma's "Add new widget" (KDE Store)
• AUR
• Manually from the latest source code

Describe the bug
playback stream stays running despite being muted

Steps to reproduce
mute the wallpaper, then observe the playback stream with something like pw-top, you'll see that its still marked as "Running"

Expected Result
To mark itself as idle when muted.

Additional context
this ruins stuff such as native sample rate switching, since pipewire likes to lock the samplerate to that of whichever playback stream is first (or last) attached to the output device.

This looks like a bug to me, or perhaps something that is not supported yet in Qt Multimedia, or at least in QML it doesn't seem to be a way to do it.

Even when the video is paused the node status stays RUNNING

This needs to be reported to Qt

I tried making MediaPlayer.audioOutput change between null and AudioOutput based on the muted state and it worked, but the switch makes the video stutter so that won't be an option.
