feat(hackathons): add judging dataset to export dropdown (#577)

Surface a new "Judging" entry alongside the existing export options
(Winners, Submissions, etc.) so organizers can download judging
criteria, judges, aggregated results, per-judge scores, and judge
comments. Requires the matching backend dataset to be deployed.
