Admin dashboard & round management UX overhaul

- Extract round detail monolith (2900→600 lines) into 13 standalone components
- Add shared round/status config (round-config.ts) replacing 4 local copies
- Delete 12 legacy competition-scoped pages, merge project pool into projects page
- Add round-type-specific dashboard stat panels (submission, mentoring, live final, deliberation, summary)
- Add contextual header quick actions based on active round type
- Improve pipeline visualization: progress bars, checkmarks, chevron connectors, overflow fix
- Add config tab completion dots (green/amber/red) and inline validation warnings
- Enhance juries page with round assignments, member avatars, and cap mode badges
- Add context-aware project list (recent submissions vs active evaluations)
- Move competition settings into Manage Editions page
