Resolve mapped/boolean items in unassign_representation_item_style #6931

Browse Source 
Use ifcopenshell.util.representation.resolve_base_items on the active
representation to reach the geometry items that actually carry styles,
unwrapping IfcMappedItem (Revit families) and IfcBooleanResult (openings)
instead of the previous shallow, all-representations walk.
