V1.0.0

Implement API request handling with Alamofire Session and token refresh

• Added APIService class to manage API requests with retry logic using Alamofire's Session.
• Introduced a RetryPolicy interceptor to handle automatic retries up to 3 times with exponential backoff.
• Implemented token management, including handling token expiration and refreshing the token using a refresh token.
• Ensured secure and robust error handling, retrying requests when the token expires, and updating the access token.
• Improved API request execution flow by decoupling the token refresh mechanism from the core request process.
