fix: backfill binaryDecision, fix boolean criterion lookup, add assign buttons

- Backfilled 166 evaluations' binaryDecision from criterionScoresJson on production DB
- Fixed roundEvaluationScores and ai-ranking to look in EvaluationForm.criteriaJson
  instead of round.configJson for the boolean "Move to the Next Stage?" criterion
- Added advanceMode (count/threshold) toggle to round config Advancement Targets
- Added "Assign to Jurors" button on Unassigned Projects section and Projects tab bulk bar
