feat(final-docs): judges see all teams' prior-round files; revised uploads behind admin toggle

The finals jury needs the teams' EXISTING submissions (pitch deck, exec summary,
business plan, videos from prior rounds) — which all 9 teams already have. So:

- listFinalistDocumentsForReview now returns ALL of each finalist team's files
  across every round (labeled by doc type + round; finale uploads flagged
  'Revised for finals'), with presigned URLs. NOT gated — judges always see.
- Revised re-uploads are now an admin toggle (Round.configJson.allowFinalistRevisedUploads,
  default OFF): gates the banner/panel (getFinalDocumentStatusForProject), the
  upload guard (getUploadUrl/deleteFile), the documents-page round, and the
  reminders (manual + cron). When off, teams aren't prompted/able to upload.
- finalist.get/setRevisedUploadSetting + a Switch on the admin finale overview.
- judge review component rewritten to a per-team labeled file list.
