feat: add competition heats system backend

Browse Source 
- Add 3 new database tables: divisions, competition_types, event_user_heats
- Add seed data for 6 divisions (NEW, NOV, INT, ADV, ALL, CHA) and 2 competition types (J&J, STR)
- Add API endpoints for divisions and competition types
- Add heats management endpoints in events route (POST/GET/DELETE)
- Implement unique constraint: cannot have same role in same division+competition type
- Add participant verification before allowing heats management
- Support heat numbers 1-9 with optional Leader/Follower role
