feat(client): configure HttpClient with AuthRedirectHandler

- Add using statement for JdeScoping.Client.Http namespace
- Register AuthRedirectHandler as a scoped service
- Replace simple HttpClient registration with handler pipeline
- AuthRedirectHandler intercepts 401 responses and redirects to login
- Keep all existing service registrations for backward compatibility
