docs(board): record MedCare#112 + smb-office#31 adjacent landings to PR #364

Sprint-5 cross-repo coordinated landing complete: MedCare-rs#112 (PR-B,
UnifiedBridge<MedcareBridge> + medcare-rbac/realtime substrate) and
smb-office-rs#31 (PR-C, UnifiedBridge<OgitBridge> wiring) both merged
2026-05-13 same day as lance-graph #364 + ndarray #142.

Updates:
* PR_ARC #364 Confidence line: append "Adjacent landings (2026-05-13)"
  note listing both downstream merges. Confidence line is the only
  mutable field per APPEND-ONLY RULE point 3.
* LATEST_STATE header: rewrite to capture the full four-PR landing
  (lance-graph + MedCare + smb-office + ndarray) so cold-start sessions
  see the coordinated landing at a glance.

D-SDR-5's UnifiedBridge surface is now consumed end-to-end.
