Closes [2029](https://github.com/twentyhq/core-team-issues/issues/2029) Widgets now use a white background on mobile and in the side panel, while keeping gray in the side column. Background colors are set at the parent container level (PageLayoutVerticalListViewer/Editor) so widgets inherit the correct background, centralizing the background logic in the container components. Other variants (dashboard, record-page) specify their own background color inside `WidgetCard.tsx` file, so we should not have any regressions. --------- Co-authored-by: Baptiste Devessier <baptiste@devessier.fr>
