fix: scope admin ranking dashboard side-sheet stats to current round

The admin dashboard fetches its side-sheet detail from project.getFullDetail
(not analytics.getProjectDetail as the audit assumed), and that procedure
had the same cross-round contamination bug. Add an optional roundId to
its input, filter the SUBMITTED-evaluations query when provided, and pass
roundId from the dashboard's useQuery so the Avg Score / Pass Rate /
Evaluators card now matches the per-juror list rendered below it.
