This is only really needed in specific cases, e.g. localUser which isn't
attached to a connection and thus needs a little help. Notes for when
this is needed is added for future readers.
(cherry picked from commit ef953b7574)
Use new KirigamiAddons ConfigurationsView as a replacement for
CategorizedSettings. Fix some issues on desktop when running Qt 6.8
and some less recent issues on mobile.
Visually this looks the same.
