Rounds overhaul: full CRUD submission windows, scheduling UI, analytics, design refresh

- Fix special award FK crash: replace 4x raw auditLog.create with logAudit() helper
- Add updateSubmissionWindow + deleteSubmissionWindow mutations to round router
- Add per-round analytics (_count, juryGroup) to competition.getById
- Remove redundant acceptedCategories from intake config
- Rewrite submission window manager with full CRUD, all fields, date pickers
- Add round scheduling card (open/close dates) to round detail page
- Add project count, assignment count, jury group to round list cards
- Visual redesign: pipeline view, brand colors, progress bars, enhanced cards
