fix(import): use SketchLineBuilder instead of model curves + AddGeometry

Browse Source 
Model curves (part.Curves.CreateLine) are SmartObjects that can't be added
to a sketch via AddGeometry. Switch to SketchLineBuilder which creates
native sketch geometry directly (SetStartPoint/SetEndPoint/Commit).
