feat(beheer): admin audit view at /beheer/audit (finishes WP-42)

The WP-41 GET /admin/audit trail now has an FE view: a beheer audit page (domain
AuditEntry + adapter/parse + store) rendering the data-minimised trail as a read-only
table, capability-gated on cases:manage. Added to ADMIN_LINKS (header nav + dashboard
Beheer section) and to the role.interceptor ROLE_AWARE list so the admin-gated call
carries X-Role. Closes WP-42's audit half.
