tdf#90297 set default SmEditWindow background

This implements ApplySetting for the proper background of the
undocked SfxDockingWindow.

In addition, like all other code, this sets the text color via
the EditEngine font objects and therefore reverts the uneeded
EditEngine interface from the original commit ea191cf9807d
("tdf#90297 use field colors for math's edit engine").
