Round detail overhaul, file requirements, project management, audit log fix

- Redesign round detail page with 6 tabs (overview, projects, filtering, assignments, config, documents)
- Add jury group assignment selector in round stats bar
- Add FileRequirementsEditor component replacing SubmissionWindowManager
- Add FilteringDashboard component for AI-powered project screening
- Add project removal from rounds (single + bulk) with cascading to subsequent rounds
- Add project add/remove UI in ProjectStatesTable with confirmation dialogs
- Fix logAudit inside $transaction pattern across all 12 router files
  (PostgreSQL aborted-transaction state caused silent operation failures)
- Fix special awards creation, deletion, status update, and winner assignment
