+Use the correct app_id when pre-authorizing remote-desktop portal access.
+
+The portal's isAppMegaAuthorized() looks up the caller's specific app_id in
+the PermissionStore.  An empty string only matches apps the portal cannot
+identify; it is not a wildcard.  Since the input handler is launched via
+KIO::CommandLauncherJob with a desktopName, the portal resolves it to the
+desktop file ID, so the empty-string entry never matches.
