Limit usage access only to owners

Problem to solve

Following up from #11481, we probably need to limit access to the new usage page to team owners in the first iteration, as discussed with @jldec and @laushinka earlier today.

This is also breaking the UX for members, see screenshots below.

Viewing as owner	Viewing as member

Closing as #11554, implemented a no access placeholder for team members. Cc @laushinka @easyCZ @jldec
