Subject: [PATCH] feat: add BomImportForm nest creation logic

Task 9: CreateNests_Click validates plate dimensions, then for each
MaterialGroup creates a Nest with name '{job} - {thickness} {material}',
sets PlateDefaults (size, thickness, material, quadrant=1, spacing),
imports each matched DXF via DxfImporter, converts entities to Program
with leading RapidMove offset handling (same pattern as CadConverterForm),
sets Quantity.Required from BOM qty, then opens an EditNestForm for each
nest that has drawings. Summary MessageBox reports count and import errors.
