feat(configurator): Three.js 3D viewer for STL files

Browse Source

Add OWL field widget (fp_3d_preview) that renders uploaded STL files
in an interactive 3D viewport:
- Three.js r170 ESM loaded lazily via dynamic import with importmap
- STLLoader + OrbitControls for full model interaction
- Fallback binary STL parser when addon import fails
- Toolbar with wireframe toggle and camera reset
- Vertex/face count display
- Theme-aware SCSS using CSS custom properties and $border-color
- Registered on model_attachment_id in the Part Catalog form

Vendored libs: three.module.min.js (691KB), STLLoader.js, OrbitControls.js
