AI shortlist with approve/reject, assignment reasoning, fix review count badge

- Rewrite AIRecommendationsDisplay: show project titles, per-project
  checkboxes, Apply and Mark as Passed button with batch transition
- Show AI jury assignment reasoning directly in rows (not tooltip)
- Fix unassigned projects badge using requiredReviews instead of hardcoded 3
- Add aiParseFiles to EvaluationConfigSchema
