feat(O): UI-Vollständigkeit + v3-Workflows + OCC-Kantenanalyse

Backend:
- Phase I: notification_configs router (GET/PUT/{event}/{channel}/POST reset)
  war bereits in notifications.py — add-alias endpoint in uploads.py ergänzt
- OutputType schema: workflow_definition_id + workflow_name fields;
  PATCH unterstützt Workflow-Zuweisung; _enrich_workflow_names() batch query
- Dispatch-Integration: orders.py dispatch_renders() → dispatch_render_with_workflow()
  mit Legacy-Fallback; neues Logging
- uploads.py: POST /validations/{id}/add-alias für Material-Lücken

Pipeline:
- step_processor.py: extract_mesh_edge_data() via OCC — berechnet Dihedralwinkel
  aller Kanten, liefert suggested_smooth_angle + sharp_edge_midpoints
  Integriert in extract_cad_metadata() und process_cad_file()
- domains/rendering/tasks.py: apply_asset_library_materials_task (K3),
  export_gltf_for_order_line_task → Blender export_gltf.py (K4),
  export_blend_for_order_line_task → export_blend.py fix (K5)
- render-worker/scripts/still_render.py: _mark_sharp_and_seams() mit
  OCC midpoint KD-tree matching + UV-Seam-Markierung
- render-worker/scripts/blender_render.py: identische Funktion + mesh_attributes parsing

Frontend:
- Layout.tsx: Upload-Link in Sidebar (alle User); Asset Libraries Link (admin/PM)
- App.tsx: /asset-libraries Route
- AssetLibrary.tsx: neue Seite (Upload, Catalog-Anzeige, Refresh, Toggle, Delete)
- OutputTypeTable.tsx: Workflow-Dropdown + Legacy/Workflow Badge
- ProductDetail.tsx: Geometry-Karte (Volumen, Surface, BBox, Sharp-Winkel)
- api/outputTypes.ts + api/products.ts: neue Felder
- api/imports.ts: ImportValidation API
