fix: resolve React Hook dependency warnings in useEffect

Fixed all 5 ESLint warnings by wrapping functions with useCallback and adding proper dependencies:
- app/admin/tirages/page.tsx: checkExistingDraw, loadParticipants
- app/admin/utilisateurs/[id]/page.tsx: loadUserDetails
- app/historique/page.tsx: loadUserTickets, filterTickets
- app/mes-lots/page.tsx: loadTickets
- components/admin/UserManagement.tsx: loadUsers
