Integrate user role retrieval into AuthContext for RBAC-ready frontend state

[alizahh-7]

Problem

Currently, the authentication context stores the user token but does not expose the user's role globally. This makes it difficult to implement role-based UI behavior and RBAC features in the frontend.

Proposed Solution

Extend the AuthContext to retrieve and store the user role after authentication using the existing fetchUserRole function.

This would:

• Fetch the role after login
• Store the role in the global authentication state
• Expose the role via useAuth() for UI components

Expected Outcome

• The frontend will have access to the authenticated user's role, enabling future implementation of:
• Role-based UI rendering
• Permission-based access control
• RBAC features across the application

Proposed Implementation
Fetch the role using fetchUserRole(token, username) after authentication and store it in the AuthContext state.

Hi maintainers,

I also wanted to mention that while working on this, I noticed that the istSOS4-gui repository has not had much recent activity.

I have already opened a pull request there implementing this improvement (integrating user role retrieval into AuthContext for RBAC-ready frontend state).

Could you please confirm whether GUI contributions should still be made in the istSOS4-gui repository, or if frontend development has moved to another location?

If needed, I would be happy to adapt the contribution accordingly.

Thank you!
