The user-detail console gains a Deletion & retention panel: last login (time + IP), the tombstone (deleted-at + retained real name), and the retention journal (the legal dossier of detached credentials). A Delete-user action runs the same deletion orchestration as the in-app flow (mirrors the email-erase pattern). Store readers RetainedIdentities + DeletionInfo back the view; integration test covers them.
