[pve-devel] [PATCH pve_flutter_frontend v2] ui: replace deprecated `onBackground` property

As of flutter v3.22, the `onBackground` property is deprecated. The
material guidelines suggest using the `onSurface` property instead.
https://m3.material.io/styles/color/roles#8562cf18-5cc0-44ae-b783-2e38bdb39585
For dark theme, the `onSurface` color and `onBackground` color is
different so it's not possible to directly replace the `onBackground`
with the `onSurface` property.To fix the issue, add a new
`onSurfaceVariant` property to the theme and replace all
instances of `onBackground` with `onSurfaceVariant`.
