Dach: getrennter Überstand Traufe/Ortgang (statt ringsum)
Bisher ein einziger overhang ringsum (Designdoc-Prio #2). Neu Roof.overhangGable für den Ortgang (Giebelseite, entlang First); overhang gilt für die Traufe (senkrecht zum First). Fehlt overhangGable, gilt ringsum overhang (rückwärts- kompatibel). Geometrie mappt die Überstände je nach ridgeAxis auf die Outline- Achsen. Panel: zweites Feld 'Überstand Ortgang' (ausser flach/zelt). +3 Tests. 672/672 grün.
