[Notif redesign] Update compact HUNs

Note that notification_2025_template_compact_heads_up_base and
notification_2025_template_compact_heads_up_messaging are forks of
notification_template_material_compact_heads_up_base and
notification_template_material_messaging_compact_heads_up respectively.

The new layouts now:
- use the new expander design
- show the top line icons with font scaling
- use the larger font size for the title

The icon size remains the same.
