fix(pm): make the pm-state ONE-OF, queue rot and contract-review carrier pair machine-judgeable (H29/H30/H31) (#11884)

Part of the half-state patrol's rule families: the general pm-state
exclusivity row, the pm:queue staleness row, and the dual-carrier
contract-review gate comparison. Report-only, no label ever written from
the script.
