Fix AI filtering bugs, add special award shortlist integration

Part 1 - Bug Fixes:
- Fix toProjectWithRelations() stripping file fields needed by AI (detectedLang, textContent, etc.)
- Fix parseAIData() reading flat when aiScreeningJson is nested under rule ID
- Fix getAIConfidenceScore() with same nesting issue (always returned 0)

Part 2 - Special Award Track Integration:
- Add shortlistSize to SpecialAward, qualityScore/shortlisted/confirmed fields to AwardEligibility
- Add specialAwardId to Round for award-owned rounds
- Update AI eligibility service to return qualityScore (0-100) for ranking
- Update eligibility job with filteringRoundId scoping and auto-shortlist top N
- Add 8 new specialAward router procedures (listForRound, runEligibilityForRound,
  listShortlist, toggleShortlisted, confirmShortlist, listRounds, createRound, deleteRound)
- Create award-shortlist.tsx component with ranked table, shortlist checkboxes, confirm dialog
- Add "Special Award Tracks" section to filtering dashboard
