Implement Role-Based Access Control

[Somya2010]

Description

Add role-based access control (RBAC) to the application, ensuring that users with different roles (e.g., admin, user) have appropriate access to resources.

Steps to Implement

1. Add a role field to the user schema (e.g., admin, user).
2. Implement middleware to check the user’s role and enforce access control on certain routes.
3. Create routes that only admin users can access (e.g., managing users).

Expected Outcome

Users will have roles, and only users with the correct roles can access specific routes.
