(core) Add document usage banners

Browse Source 
Summary:
This also enables the new Usage section for all sites. Currently,
it shows metrics for document row count, but only if the user
has full document read access. Otherwise, a message about
insufficient access is shown.

Test Plan: Browser tests.
