Add TypeScript types for auth

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

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

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

The title requests TypeScript auth types, while the body requests data sorting through an `enable_sorting` config option, so clarify the intended change first. No files, tests, or entry points are named; after scope is confirmed, locate the config handling and sorting path, then add coverage showing the default-disabled behavior and enabled sorting.
