[pve-devel] [PATCH pve_flutter_frontend] ui: replace use of `background` property

[Shan Shaji]

As of flutter v3.22 the `background` property is
deprecated. The material guidelines suggest
using the surface color for backgrounds.

https://m3.material.io/styles/color/roles#8562cf18-5cc0-44ae-b783-2e38bdb39585

Due to the difference between the current background color and surface
color, this patch assigns the colors `supportGreyTint75`(light theme) and
`grey`(dark theme) to the `surfaceContainer` property,
replacing all instances of `background` with `surfaceContainer`.
