Dismissing admin notices is an admin-only action. This is enforced on the back-end both by a routing constraint and a policy in the relevant service.
However, we still unconditionally display the "Dismiss" button to anyone with access to the admin dashboard. When clicked, it results in a 404 modal (due to the routing constraint.)
With this change we only render the dismiss button for admins.
his is a new feature that lets admins dismiss notices from the dashboard. This helps with self-service in cases where a notice is "stuck", while we work on provisions to prevent "sticking" in the first place.
