Fix evaluation criteria, jury preferences, assignment config, and dashboard stats

- Fix criteria not showing for jurors: fetch active form independently via
  getStageForm query instead of relying on existing evaluation record
- Fix scoringMode default from 'global' to 'criteria' (matching schema)
- Parse scale string format ("1-10") into minScore/maxScore for criteria display
- Fix COI dialog dismissal: prevent outside click on evaluate page Dialog
- Fix requiredReviews hardcoded to 3: read from round configJson in 4 locations
- Add jury preferences banner for unconfirmed caps on jury dashboard
- Add updateJuryPreferences tRPC procedure for self-service cap/ratio
- Simplify onboarding: always show jury step, allow cap up to 50
- Add role/ratio/availability fields to jury member invite dialog
- Simplify jury group settings (keep only defaultMaxAssignments)
- Enforce deliberation showCollectiveRankings flag for non-admin users
- Redesign dashboard stat cards: editorial data strip on mobile,
  clean grid layout on desktop (no more generic card pattern)
