AI Summary: Redesign the login and register UI layouts for a CMS landing page. The current left-right split design needs to be replaced with a more modern, centered or stacked layout while maintaining existing form elements and ensuring responsiveness. The updated layout should be implemented in `src/features/auth/components/AuthLayout.tsx` and applied to both login and register pages, adhering to the existing styling and accessibility standards.
