This patch refactors the DBus integration in both QGnomeTheme and QGtk3Theme to centralize and simplify the portal and settings access logic. Previously, the codebase contained duplicated and scattered DBus logic for querying GNOME/GTK appearance settings, such as color scheme and contrast, which were implemented separately in both QGnomeTheme and QGtk3Theme. The patch introduces a new QGnomePortalInterface class which encapsulates all DBus interactions related to GNOME/GTK appearance settings. The old DBus interface logic is removed from QGtk3Theme and QGnomeTheme, and replaced with calls to the unified QGnomePortalInterface. The update also ensures signal-based updates for theme and appearance changes via the new interface.
