feat(activity): merge CAD + render jobs into unified timeline

- Single chronological list sorted by updated_at (newest first)
- Type badges distinguish CAD processing (FileCode2) from Render jobs (Image)
- Render job rows now link directly to the order (/orders/:id)
- Remove separate "Render Jobs" and "CAD File Processing" sections
- Stat cards simplified to 4: CAD active/failed + Render active/failed
- Backend: add order_id to RenderJobEntry response
- Frontend: add order_id to RenderJobEntry interface, remove flamenco_job_id
