Hartmut 72123c5aa9 fix(export_gltf): clear OCC custom_normal attribute before sharp edge processing

The geometry GLB from export_step_to_gltf.py contains a 'custom_normal' attribute
(CORNER, INT16_2D) from OCC tessellation. If left in place, Blender's glTF exporter
re-exports these pre-baked normals unchanged — ignoring shade_smooth_by_angle
processing and our explicit sharp edge marks.

Fix: remove the 'custom_normal' attribute from all imported mesh objects immediately
after GLB import, before applying smooth shading. Also add orphans_purge() before
export to remove palette materials (mat_0/1/2/3) that become users=0 after library
material substitution.

Same custom_normal clearing applied to blender_render.py for thumbnail renders.
