Implement JWT Token Authentication for Enhanced Security

[AshhubAli]

This issue aims to integrate JSON Web Token (JWT) authentication to bolster the security measures within our system. Implementing JWT tokens will provide a robust method for user authentication and authorization, enhancing the overall security posture of our application.

Key Objectives:

1. Token-Based Authentication: Introduce JWT tokens as a secure method for user authentication, ensuring encrypted and tamper-proof authorization tokens.
2. User Session Management: Implement token-based user sessions to enhance security while maintaining a seamless user experience.
3. Authorization Mechanism: Develop an authorization mechanism using JWT tokens to regulate user access based on roles and permissions.
4. Token Expiry and Renewal: Configure token expiry to enhance security and implement a mechanism for token renewal to maintain user sessions.

Expected Outcomes:

• Strengthened security measures through the adoption of JWT token-based authentication.
• Improved user authentication and authorization workflows.
