feat(plating): Sub 4 — Contract Review (optional, QA-005 1:1 PDF)

Per-part contract review record (fp.contract.review) gated by a
customer-level toggle, signed in two sections (QA Assistant → QA
Manager), settings-based signer rosters (no new res.groups), banner on
the part form that auto-dismisses once the first MO for the part hits
confirmed. QA-005 Rev. 0 paper form reproduced 1:1 in a QWeb PDF.

Never blocks MO/SO/WO — review is purely an audit artefact.

Smoke test run on entech: 12 assertions pass including the 25-cell
risk matrix parity with the paper form and 22 KB PDF render.
