Add TypeScript types for auth

**Feature request**
It would be great to have sorting for auth.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_sorting` with default `false`.

Resolve the scope mismatch between the title, which requests TypeScript types for auth, and the body, which requests sorting with an `enable_sorting` config option. Start by locating the auth configuration and related TypeScript definitions; confirm the intended behavior, default value, affected entry points, and tests before implementing.
