Specify background per screen size

[ArmofDAO]

Description

I would appreciate the ability to set different wallpapers to use between mobile and desktop use. I appreciate the different icon scaling settings between small/medium/large screens, but Homarr only allows for one background to be set between the three sizes.

Having the ability to set one wallpaper for large mode on desktop, and a different one for small on mobile would allow for a background to be customized to fit properly when viewing on either desktop or mobile, rather than having to choose which device you want to optimize the aesthetics for.

Priority

Low (Nice-to-have)

I think this might be doeable with custom css

This is no longer needed for 1.0 as there are no longer the gridstack sizes
