Implement Automatic Sign-in Using Refresh Token

[JavidSumra]

Issue : #44

Description: This pull request aims to enhance user experience by implementing automatic sign-in functionality using refresh tokens. Instead of navigating to the traditional login page when the user clicks the login button, this feature enables the application to automatically sign in the user using their refresh token.

Changes Made:

• Modified the behavior of the login button to trigger automatic sign-in using the user's refresh token upon click.
• Implemented logic to securely retrieve the refresh token from storage and use it to request a new access token from the authentication server.
• Implemented error handling mechanisms to gracefully handle cases where automatic sign-in fails due to various reasons, such as expired or invalid refresh tokens, network issues, or server errors.
• Provided visual feedback to users to indicate the progress of the automatic sign-in process, ensuring transparency and user awareness of the authentication status.

Testing:

• Conducted thorough testing of the automatic sign-in functionality to validate its reliability and performance across different scenarios.
• Tested various scenarios, including valid and invalid refresh tokens, network failures, and edge cases, to ensure robustness and responsiveness.

This enhancement aims to streamline the authentication process and provide users with a seamless login experience while maintaining security and reliability. Feedback and suggestions for further improvement are welcome.
