Manage page — lists the current user's personal dashboards, all shared
(system) dashboards, and any role-scoped dashboards for the user's roles.
Creating and editing metadata happens on the dedicated form page
(DashboardFormLive); from here admins open the builder, clone any
visible dashboard into a private editable copy, edit, or delete (own
personal ones + shared/role ones).
Admin layout, sidebar, and the @phoenix_kit_current_user / _scope assigns
are injected by PhoenixKit's on_mount hooks.
