Description:

Implement a requirement for users to have a Tanam role in their custom claims to access the CMS. The following tasks need to be accomplished:

1. Role Validation:

   • Check if the user has any Tanam role in their custom claims.

2. Access Denied Handling:

   • Redirect the user to an "Access Denied" error page if they do not have the required claim.

3. Access Denied Page:

   • Create an "Access Denied" error page to inform users they do not have the necessary permissions to access the CMS.

Acceptance Criteria:

• Users without a Tanam role in their custom claims are redirected to the "Access Denied" error page.
• An "Access Denied" error page is created and displays a clear message informing users of the permission issue.

Notes:

• Ensure robust error handling and logging for the role validation and redirection process.
• The "Access Denied" error page should be styled consistently with the rest of the application.
• Documentation should be updated to reflect these changes.
