/**
 * Dashboard endpoints must not leak other admins' data to event-scoped
 * editors — GHSA-c2jj (/stats), GHSA-gqx7 (/analytics), GHSA-jhcf (/activity).
 *
 * All three are gated only by `analytics.view`, which the `editor` role holds.
 * But the events LIST restricts editors to their own rows
 * (adminEvents/crud.js: roleName === 'editor' → created_by = admin.id), so an
 * editor saw instance-wide totals — and, via /analytics topGalleries, other
 * admins' gallery names and SLUGS (the public gallery URL component) — for
 * events invisible to them everywhere else.
 *
 * Scoping deliberately keys on `editor` to mirror the events list exactly, so
 * the `admin` role's dashboard is unchanged.
