/**
 * Full-instance export is super_admin only (GHSA-pv6w-rj34-wj9v).
 *
 * GET /api/admin/backup/picpeak/export dumps every table unredacted (bcrypt
 * hashes, 2FA, SMTP/SSO/WhatsApp/webhook/S3 secrets). It was gated only by
 * requirePermission('backup.create'), which the built-in `admin` role holds —
 * so any non-super_admin admin could download the whole database. Pins that
 * `admin` now gets 403 and `super_admin` passes the gate.
