fix(storage): restore the pointer to where retention is configured

The breakdown is the only place on the org usage page that tells a user how to
act on the noncurrent bytes they're being billed for, and the navigation path had
been trimmed out of it.

Also flags why the per-bucket rows aren't links: buckets are per-project and this
is an org-level page, so the endpoint needs to return a project ref before a row
can be linked — or even disambiguated, since two projects can both have an
`avatars` bucket.
