New WRITE-gated triage route lists provisional persons (one PersonReviewRow
each) with Merge (reuses POST /merge), Umbenennen (PUT), Bestätigen
(PATCH /confirm) and Löschen (DELETE behind the focus-trapped, Escape-dismissible
ConfirmDialog service). Actions run as form actions via use:enhance so they work
without JS and stay server-side permission-guarded; the loader is READ_ALL.
