fix(dashboard): hide the tenant picker on cluster-scoped admin pages

The Breadcrumb subtitle is a tenant picker, and it rendered on every
route including the cluster-wide /admin Capacity views, where picking
a tenant changes nothing. Reuse the inAdmin flag that already selects
the sidebar sections to drop the subtitle there.

Fixes #3106
