Fixed the Windows GTK3 native file chooser lifetime handling by adding an idle callback (gtkutil_native_dialog_unref_idle) that performs g_object_unref(native) outside the button-release signal stack. This avoids the crash path when cancelling the Load file dialog.

Updated the native chooser code path to replace immediate unref with deferred unref via g_idle_add(...) after gtk_native_dialog_run, while preserving the existing accept-only file handling behavior.
