ship: drop issue/incident IDs and the 'continue silently' suppressor (s06 M2, s06 M3, s06 M4, s06 M7)

- M2/M3: '(#1946)' and '(#1079)' removed from the credential guard and REST
  fallback headings; the rules are unchanged.
- M4: the audit-failure fallback states the reason (a skipped audit lets
  unverified plan items ship as done) instead of 'the failure shape that
  VAS-449 surfaced'.
- M7: 'Continue silently — just note the counts briefly' -> report the pass
  counts in one line and continue to Step 6 (Step 16 cites these counts).

Not changed: s06 M1, the Step 16 IRON LAW (UC2 gate keeps its wording).
W7a pin: test/ship-plan-completion-invariants.test.ts:127 pinned the VAS-449
sentence; it now checks that the audit-failure fallback still forbids a
silent fail-open (case-insensitive). Negative control: deleting that
sentence turns it red. expected red until the regeneration commit
