Refactor token exchange implementation in OAuth service
- Updated the TokenExchange method to utilize a new generateExchangedToken function for improved token generation. - Enhanced error handling to return a descriptive error response if token generation fails. - Added a new generateExchangedToken function to encapsulate the logic for creating exchanged tokens, improving code organization and maintainability.
