Phase 6: Q.C. inspection, project folders, packet documents and the digital ITP

The Q.C. screen (KPIs, boards, project folders), the Q.C. tab on the packet
page (check items from the qc_check_items settings row, visual exam per weld,
NDE, hardness with the NACE label, notes), accept with a route and a
signature gated by qc_missing_empty, reject with a reason or an NCR number
closing the inspection into qc_history, Q.C. folder documents per project and
unit with superseding revisions, packet documents as a closed set with
take-out reasons, the digital ITP per unit from the frozen template (line
initials with CAS, unsign, N/A, customer codes, rejects with NCR, block
signatures, sign-off with the PDF hook, admin reopen, the ITP log), hold-point
warnings by department page group, the scoped policy check for unit and
project writes, migration 0007, tests, Playwright scenarios and docs.
