feat: add OLE2Frame interactivity + fix Shape rotation from DXF

OLE2Frame: full TruckConvertible/Grippable/PropertyEditable/Transformable
impls in src/entities/ole2frame.rs — grips on corners + center, properties
panel, translate/scale transforms.

Shape: rotation (DXF code 50) now converted degrees→radians on load in
fix_dxf_dimension_rotations(), matching Dimension and Attribute behaviour.

All ❌ gaps resolved. Remaining: Viewport GPU scissor, LWPolyline plinegen.
