fix: add type assertion for PRIZE_CONFIG access in historique page

Add type assertion to handle prize types that may not exist in PRIZE_CONFIG.
This is the same fix applied to app/client/page.tsx to prevent TypeScript
compilation errors when accessing PRIZE_CONFIG with dynamic prize types
(PHYSICAL, DISCOUNT, GRAND_PRIZE).
