[fix.pose.λ.D8+] preserve atom-pair evidence through campaign projections

The prepared pose objects contained exact nearest, contact, and clash atom-pair
witnesses, but the campaign preparation response and prepared-system listing
projected only scalar summaries.  The reviewer therefore correctly refused
otherwise valid live 1CBS poses because it could not see server evidence.

Carry the complete server pose report through both projections, require its
geometry and atom-pair fields in the public system-list contract, and make pose
acceptance independently reject a missing nearest-pair witness.  This keeps the
visible human review and the server execution gate on the same evidence object.
