Multi-role members, round detail UI overhaul, dashboard jury progress, and submit bug fix

- Add roles UserRole[] to User model with migration + backfill from existing role column
- Update auth JWT/session to propagate roles array with [role] fallback for stale tokens
- Update tRPC hasRole() middleware and add userHasRole() helper for inline role checks
- Update ~15 router inline checks and ~13 DB queries to use roles array
- Add updateRoles admin mutation with SUPER_ADMIN guard and priority-based primary role
- Add role switcher UI in admin sidebar and role-nav for multi-role users
- Remove redundant stats cards from round detail, add window dates to header banner
- Merge Members section into JuryProgressTable with inline cap editor and remove buttons
- Reorder round detail assignments tab: Progress > Score Dist > Assignments > Coverage > Jury Group
- Make score distribution fill full vertical height, reassignment history always open
- Add per-juror progress bars to admin dashboard ActiveRoundPanel for EVALUATION rounds
- Fix evaluation submit bug: use isSubmitting state instead of startMutation.isPending
