Adjust spec for unpublished draft comments section

Rename to "Has draft comments" to reduce confusion, and add a
dashboard-only suffix of "limit:10" to impose a maximum height. This
should help users who have an enormous number of changes in this
section, at least until we can introduce UI to help them clear out these
existing draft comments.
