- Created `/frontend/app/api/votes/check/route.ts` to handle GET requests for checking if a user has voted in a specific election. - Added error handling for unauthorized access and missing election ID. - Forwarded requests to the backend API and returned appropriate responses. - Updated `/frontend/app/api/votes/history/route.ts` to fetch user's voting history with error handling. - Ensured both endpoints utilize the authorization token for secure access.
