tdf#136555 apply window bg color for button boxes

The default background color of the frame is APPBACKGROUND, which
is matched to GetWorkspaceColor(). That color is visible in Writer
as the default document workspace background.

Originally I just saw the dark background of the button box in the
start center, and thought the workspace color in Qt is wrong and
changed it in the reverted commit, missing the change of the color
around the Writer document.

Now that the button boxes's background color isn't fixed via the
"branding" setting, we also must react to changed style settings,
so we override the DataChanged function.

This also reverts commit e0c72e31c1d455c26110c35e8780d420e17cdea6.
