Problem description

PR #10552 submitted by @Syres916 significantly improved the FEM legend - now it's much less likely to be partially covered by the navigation cube and the labels are more visible (plus there are settings for their font in Preferences). However, there are still 2 small issues mentioned in this comment: https://github.com/FreeCAD/FreeCAD/pull/10552#issuecomment-1729950881

So under some screen resolutions, the legend can still get partially covered by the navigation cube. Also, larger label font sizes may lead to values going beyond the screen.

It should be possible to fix it but if it turns out to be too troublesome, my idea is to just move the legend to the left side of the screen (as shown in this comment: https://github.com/FreeCAD/FreeCAD/pull/10552#issuecomment-1735549319). Any potential issues with this approach ?
