feat: Add the background UI in the app selection screen

[A1692jk]

Feature description

So when we select an app the UI or particles we have selected to come behind as the wallpaper, space, hex, snow whatever, doesn't come when we select an app. I request for allowing the particles to appear on the app screen menu (I am not sure how it would look it might be bad)

Motivation

Allows the live wallpaper to come in the app selecting screen. May make the UI look good... but may also make it look bad
