Volume applet fails to load correctly, showing empty UI due to missing Kirigami QML components (InlineMessage, ActionToolBar). Screenshot attached

SUMMARY
Summary:
Volume and Network Management Plasma applets fail to load correctly due to missing Kirigami QML components (InlineMessage, ActionToolBar, PopupDialog, ConnectionListPage). This happens even after clearing QML cache. Other Plasma components (systemsettings, Breeze) work correctly.

STEPS TO REPRODUCE
1 Run Plasma 6.5.80 on openSUSE Tumbleweed with KF6 6.20.0 and Qt 6.10.
2 Add the default Volume or Network Management applet to the panel.
3 Open applet.
Observed Result:
- Applet UI is broken or empty.
- Log errors:

Volume and Network Management applets load and display correctly, without errors.


EXPECTED RESULT
Volume and Network Management applets load and display correctly, without errors.
