Schnitt-Tiefe: Kanten hinter DrawingLevel.depth ausblenden
computeSection filtert Ansichtskanten (sichtbar/verdeckt), deren Quell-Bauteil weiter als level.depth hinter der Ebene liegt (Owner-Distanz-Naeherung ueber den Bauteil-Mittelpunkt; Cut-Polygone bleiben). Naeherung dokumentiert (TODO: exakte per-Kante-Tiefe aus render3d/section.rs). Feld ist in der Schnittlinien-Sektion editierbar (Teil 3). Test fuer filterByDepth.
