feat(plating): close compliance gaps 7-9 — NCR + CAPA + discharge + invoice ref

**7a. NCR close gate** (fusion.plating.ncr.action_close)
Block close unless these are filled in:
  • Description (what happened)
  • Containment Actions (immediate response)
  • Root Cause (why it happened)
  • Disposition (use-as-is / rework / scrap / RTV decision)

A closed NCR without these is useless for AS9100 audits — it's
the entire point of an NCR to document what went wrong, why, and
how we responded. Empty-HTML strings like "<p><br></p>" are
detected as empty too.

**7b. CAPA close gate** (fusion.plating.capa.action_close)
Block close unless:
  • Root Cause Analysis filled in
  • Action Plan filled in
  • Verification (date + verifier) recorded
  • Effectiveness Notes filled when CAPA was marked Not Effective

AS9100 §10.2 / Nadcap require evidence of root-cause analysis,
the corrective/preventive action plan, AND that effectiveness
was verified before the loop is closed.

**8. Invoice ref defensive default** (account.move.create)
Auto-fills `ref` from the source SO's client_order_ref or
x_fc_po_number when the invoice is created with invoice_origin set
but no ref. Already populated on the SO confirm path; this catches
manually-created invoices that would otherwise miss it. Customer
AP teams reject invoices that don't quote their PO# back.

**9. Discharge sample close gate** (fusion.plating.discharge.sample.action_close)
Block close unless:
  • Lab Report # set
  • Results Received Date set
  • At least one parameter reading on file
  • Lab certificate/report attached

Without lab evidence the record fails any environmental compliance
audit — the whole point is to document the test was performed and
what the lab said.

**Simulator** (scripts/fp_e2e_workforce.py)
Adds 4 new negative tests (Test 8-11), all wrapped in savepoints:
  ✓ Test 8 : NCR close without RC/containment/disposition → blocked
  ✓ Test 9 : CAPA close without analysis/plan/verification → blocked
  ✓ Test 10: Discharge sample close without lab evidence → blocked
  ✓ Test 11: Invoice ref auto-fills from SO.client_order_ref → asserted

**Final E2E**: 52 PASS / 2 WARN / 0 FAIL out of 54 checks.
Both remaining WARNs are expected (bake-window auto-create,
first-piece gate — coating-driven, this coating doesn't trigger them).

11 negative tests in total now, every gate fires when triggered.
