Audio visualizer animation continues when music is paused

[SethFalco]

Describe The Bug

When listening to music on Jellyfin, the queue page replaces the cover image of the playing track with a GIF. However, when the music is paused, the animation continues.

On the side, this GIF could probably be replaced with an SVG.

Steps To Reproduce

1. Go to a music library
2. Click on the play button for an album
3. Click on the bar at the bottom to get taken to /queue
4. Pause the music

Expected Behavior

I would expect one of the following:

1. The animation pauses.
2. The image is replaced with a pause icon. ⏸️

I think number 2 would be better and easier to implement. You can probably just use the pause Material Icon (here) since that's already in Jellyfin anyway.

Screenshots

Just pretend you can see the GIF still moving. ^-^'

System (please complete the following information):

• Platform: Linux
• Browser: Firefox / Jellyfin Media Player
• Jellyfin Version: 10.7.6

Additional Context

This is just a minor UX concern, it can throw a user off when part of the UI suggests that music should be playing when it's not.
