FIX(theme): Fix theme regression in Qt6

Hartmnt · Hartmnt · commit bef61ab078c1 · 2025-04-07T17:02:45.000Z
With the switch to Qt6 the TreeView rows now have
a different padding/margin which lead to an ugly
theme artifact on the left side of any TreeView.

This commit adjusts padding/margin and the background
color of the ::branch element to the new Qt6 reality.
