/**
 * The sidebar is derived from the same permission catalog the API guards use.
 *
 * An operator who cannot read orders never sees an Orders link, so the UI has
 * no dead ends. This is presentation only — hiding a link is not authorization.
 * The API re-checks every request, because a hidden link is one devtools
 * inspection away from being visible.
 *
 * Labels are message keys rather than strings: the sidebar is the most visible
 * surface in the admin, and hard-coding English here would have made the
 * language switcher look broken.
