Admin system overhaul: full round config UI, flattened navigation, juries, awards integration, evaluation rewrite

- Phase 1: 7 round config sub-components covering all ~65 Zod schema fields across INTAKE, FILTERING, EVALUATION, SUBMISSION, MENTORING, LIVE_FINAL, DELIBERATION
- Phase 2: Replace Competitions nav with Rounds + add Juries; new /admin/rounds and /admin/rounds/[roundId] pages with tabbed detail (Config, Projects, Windows, Documents, Awards)
- Phase 3: Top-level /admin/juries with list + detail pages (members table, settings panel, self-service review)
- Phase 4: File requirements editor in round config; project detail per-requirement upload slots replacing generic drop zone
- Phase 5: Awards edit page with source round dropdown, eligibility mode, auto-tag rules builder; round detail Awards tab; specialAward router enhanced with evaluationRoundId/eligibilityMode fields
- Phase 6: Evaluation page rewrite supporting all 3 scoring modes (criteria/global/binary) with config-driven behavior; live voting UI polish
- Phase 7: UI design polish across admin pages — consistent headers, cards, hover transitions, empty states, brand colors
- Bulk upload page for admin project imports
- File router enhanced with admin upload and submission window procedures
