Phase 3.5: replace _PendingRequestsBanner with a Riwayat Permintaan card
on the mitra home, plus a screen listing the last 20 entries from
chat_request_notifications. Backend endpoint TBD.
Phase 3.6: plan to re-enable mitra force-close (Akhiri) once the moderation
/ accountability story is in place. Backend route and config flag are
already preserved from Phase 3.
