Add a capability-gated Beheer section to the dashboard listing the admin pages (Huisstijl, Stamdata, Aanvragen), each shown when the principal holds its capability — so admin pages are discoverable, not URL-only. Extract the admin link list to shared/layout/admin-links.ts as one source of truth, reused by the site header (was ADMIN_NAV_ITEMS) and the new section. Capability-gated, never role-derived (PRD-0002). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
