feat(plating): Sub 4 — Check All / Clear All buttons + fix QA-005 PDF logo render

- New bulk-toggle actions on fp.contract.review flip all 10 checklist
  items in Section 2.0 (and all 11 in Section 3.0) in one click.
  Rendered as "Check All" / "Clear All" buttons above each checklist.
  User can still tick boxes individually. Buttons hide once the
  section is signed (locked).
- Fix QA-005 PDF: replaced `to_text(...)` (not in QWeb context) with
  `image_data_uri(...)` for the company logo embed. PDF now renders
  with the full colour ENTECH logo (render size 103 KB).
- Smoke test extended: 5 new assertions covering bulk-toggle on/off
  and locked-section guard. 17/17 pass on entech.
