Areas page now shows a single TreeView with sites as roots and areas as children. Context menus: sites get "Add Area", areas get "Add Child Area", "Edit Area", "Delete Area" — each navigating to a dedicated page. The Delete Area page shows a TreeView of the area and all recursive children with assigned instances. Deletion is blocked if any instances are assigned to the area or its descendants.
