Hartmut f1e02ded78 feat(F1): wire MinIO STL cache into render_still + render_turntable_to_file 
Previously the cache_service was only used in the generate_stl_cache Celery task.
All render paths (render_still, render_turntable_to_file, render_turntable_task)
only checked for a local file and converted from scratch if missing.

Changes:
- render_blender.py: add _stl_from_cache_or_convert() helper that checks MinIO
  cache before falling back to local STEP→STL conversion. Wire into render_still()
  and render_turntable_to_file() (both STL conversion blocks).
- domains/rendering/tasks.py: wire MinIO cache check into render_turntable_task()
  inline before convert_step_to_stl(). All errors are non-fatal (falls back to
  fresh conversion).

Now a STEP file converted on one worker is available to all workers via MinIO,
avoiding redundant cadquery conversions on re-renders.

Hartmut c74e118b98 feat(E): add MediaAsset catalog — model, CRUD API, MediaBrowser UI 
Migration 040: media_assets table with RLS (tenant_isolation + admin_bypass).
domains/media/: MediaAsset model, schemas, service, router with ZIP-download.
publish_asset Celery task in rendering/tasks.py.
core/storage.py: download_bytes() method for MinIO + LocalStorage.
frontend: MediaBrowser.tsx (grid/list, multi-select, zip-download, pagination) + api/media.ts.
Route /media (AdminRoute) + sidebar link with Image icon for admin+pm.

Hartmut 716451ff76 feat(D): OCC mesh attribute extraction + Blender smooth shading integration 
Migration 039: cad_files.mesh_attributes JSONB column.
domains/products/tasks.py: extract_mesh_attributes Celery task using pythonOCC.
still_render.py + turntable_render.py: _apply_mesh_attributes() sets auto-smooth
based on curved_ratio and topology threshold from OCC analysis.
render_blender.py: passes --mesh-attributes JSON arg to Blender subprocess.
render_still_task: loads mesh_attributes from DB and passes to renderer.

Hartmut 9d1a820295 refactor(A2): replace blender-renderer HTTP service with render-worker Celery container 
- Create render-worker/ with Dockerfile (Ubuntu + cadquery + Blender via host mount)
- Add render-worker/check_version.py: verifies Blender >= 5.0.1 at startup, Exit 1 on failure
- Add render-worker/scripts/: blender_render.py, still_render.py, turntable_render.py
- Create backend/app/services/render_blender.py: direct subprocess rendering
  - convert_step_to_stl() and export_per_part_stls() using cadquery
  - render_still(): STEP → STL → PNG via Blender subprocess
  - is_blender_available(): detects BLENDER_BIN env for render-worker context
- Create backend/app/domains/rendering/tasks.py: render_still_task + render_turntable_task
- Update step_processor.py: use subprocess path when BLENDER_BIN env is set (render-worker)
- Update step_tasks.py: generate_stl_cache uses direct cadquery instead of HTTP
- Remove blender-renderer and threejs-renderer from docker-compose.yml
- Replace worker-thumbnail with render-worker (Ubuntu + cadquery + Blender mount)
- Remove Docker SDK from backend Dockerfile (was only for flamenco scaling)
- Update .env.example: BLENDER_VERSION=5.0.1 documented
- Update celery_app.py: include domains.rendering.tasks in autodiscover
