2D: Ellipse, Spline und Bezier als neue Zeichenwerkzeuge

Browse Source 
Ellipse (zwei Bounding-Box-Ecken, achsparallel), Spline (Wegpunkte, geglättet
via Catmull-Rom, wie Polylinie mit rundem statt geradem Verlauf) und Bezier
(klassische manuelle Kontrollpunkt-Kette: Anker/Griff/Griff je Segment).

Neue Drawing2DGeom-Formen + Mathe-Helfer (tools/curves.ts). Rendering
tessellliert zu Linien-/Polygon-Primitiven (wie Polylinie/Rechteck) statt
eigenem SVG-Primitiv — dadurch funktionieren DXF-/Print-SVG-Export und
Hit-Testing ohne Änderung mit. Griff-Editieren (2D-PlanView + 3D-Viewport),
Verschieben/Skalieren, Snapping (Ellipse-Mittelpunkt, Bezier/Spline-Konturen)
und Georef-Rebase entsprechend erweitert.
