pm-dispatch: restore needs:contract-review as a marker for a PR awaiting its at-tier review

The label comes back as a visibility marker only, never a gate:

- references/contract-review.md gains a 〈等复核标记〉 section: hang on
  the PR at ACCEPT when either clause-② limb hits and no same-form PASS
  is on the current head; clear when that PASS is on file or the PR
  merges or closes; single carrier = the PR; named readers = the
  maintainer's PR-list filter and each seat's patrol and handover; no
  check, workflow, queue guard or patrol script reads it.
- references/landing-operations.md: the subagent-down line names the
  marker in place (line count unchanged, 119 bytes).
- scripts/pm/ensure-pm-labels.sh: one main-repo row, colour bfdadc,
  description under the 100-character cap.

Every layer ruling record 5770886272 retired (gate role, --pair,
double carrier, independence pair) stays retired.
