Replace two-step initialization (default constructor + Initialize) with direct construction for 8 non-copyable/non-movable property and grid evaluator classes. Objects are now always in a valid state after construction. Refactored classes: - GeomProp_Curve, GeomProp_Surface (TKG3d) - Geom2dProp_Curve (TKG2d) - BRepProp_Curve, BRepProp_Surface (TKBRep) - GeomGridEval_Curve, GeomGridEval_Surface (TKG3d) - Geom2dGridEval_Curve (TKG2d) Changes per class: - Remove default constructor and IsInitialized() method. - Add constructors matching each former Initialize overload. - Rename Initialize to protected initialization method for internal and derived class use. All callers updated across production code (Extrema, BndLib, IntCurveSurface, IntPatch, HLRBRep, GeomGridEval derived classes) and test files to use constructor-based initialization.
