fix: Make focused app menu entry wider to see full name

[susnux]

• Resolves: [Bug]: App name does not show fully on hover/focus of specific app #47101

Summary

This makes the focused app entry wider while shrinking its neighbors.

In this PR (currently) I use 3grid-baseline, but this is not enough for "Dashboard", do you think 4grid-baseline is ok? Meaning it would grow by 16px to 66px focused entry.

4grid baseline seems fine to me 👍

I changed the value to 4 * grid baseline now, so the second screen recording is the current version :)
