Why do we have big red boxes now when package(s) fail(s) to update? The previous style was clean, sleek, with better colors. Please return to the original version instead of making it worse just for the sake of changing.

### Describe how this improvement could help users

Why do we have big red boxes now when package(s) fail(s) to update? The previous style was clean, sleek, with better colors. Please return to the original version instead of making it worse just for the sake of changing.

Start by reproducing a package update failure in the current UniGetUI interface and compare the red failure boxes with the original presentation described in the issue. Review the existing UI styling and prior version if available; done requires an agreed replacement that restores the cleaner colors and presentation.
