Introduce IPropertyGroupProvider interface that lets QObjects declare
which group each property belongs to. PropertyEditor then renders
collapsible group headers in the tree view, with properties sorted
under their respective groups.
Key changes:
- New IPropertyGroupProvider interface (getPropertyGroup method)
- QDetailsViewRow_Group row type with bold group header rendering
- isGroup model role and delegate property for styled group rows
- TapHandler-based expand/collapse toggle in delegate template
- One-time C++ auto-expand for groups in setObject() to avoid
re-expansion loop with delegate recreation
- Grouped property children added via LayoutBuilder::addGroup()
- GraphicsBusSectionItem demonstrates grouping with 5 categories

- Rounded rects: serialize/restore isRound, ratioX, ratioY; pass isRound
to constructor so rounded-corner control handles are created
- Polygons: implement full serialization/deserialization including vertex
points; add updateBoundingRectFromPoints() to fix hit-test and handles
after deserialization
- Groups: add updateBoundingRectFromChildren() to correctly compute
bounding rect after child items are deserialized
