This commit introduces a new Auth User management feature, allowing admins to create, update, delete, and list users in the auth database. A dedicated API has been implemented with endpoints for managing auth users, including validation for unique email addresses. The frontend has been updated to include a Manage Users page with tabs for backend and frontend users, enhancing the user experience. Additionally, modals for creating and editing auth users have been added, along with appropriate error handling and loading states. Documentation has been updated to reflect these changes.
