Fix: review UI domain breakdown from Qdrant

The review items API endpoint still read concept domain counts from
on-disk JSON files, which would show empty breakdowns for items with
missing concept directories. Replace disk reads with the same
_count_domains_from_qdrant function used by domain assignment.
