Add TypeScript types for store

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

**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 types for the store, while the body requests sortable middleware and an `enable_sorting` option. Start by locating the store and middleware configuration entry points, then clarify which scope is intended. Done should be defined as either the store types being covered or sorting being configurable with a default of `false`.
