feat(12-05): live PAX8 orders/matching verification script + quantity fix

- scripts/verify-pax8-orders-matching.ts: runs a real Pax8SyncService.fullSync()
  twice, then asserts all four Phase 12 success criteria (order items
  populated with company id + billing period, confident auto-matches exist,
  no-match/ambiguous companies flagged for review, auto-match set stable
  across two syncs). Never logs secrets/tokens.
- migrations/094_pax8_order_items_quantity_numeric.sql (Rule 1 auto-fix):
  pax8_order_items.quantity was INTEGER but real PAX8 usage-based invoice
  items (e.g. Azure per-unit bandwidth overage) report fractional
  quantities, which aborted the entire orders/order_items sync loop on the
  first such row and silently truncated SC#1's item coverage to ~123 rows
  instead of the full ~56k-row history. Widened to NUMERIC(14,4); applied
  directly to the dev DB (existing volume, not a fresh init).
- deferred-items.md: logged pre-existing out-of-scope failures (appgate
  TS2307 type errors, itglue-search.test.ts) confirmed unchanged by this
  plan's files.

+ *
+ *   SC#1: pax8_order_items populated with per-company id + billing period

+ *   SC#3: no-match / ambiguous companies are flagged in
