Add TypeScript types for utils

**Feature request**
It would be great to have analytics for core.

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

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

First reconcile the title's request for TypeScript types with the body’s analytics feature request; the payload names no files, tests, or entry points. Identify the configuration definition and its type declarations, then verify that the intended change is represented by an `enable_analytics` option defaulting to `false` and covered by the project’s relevant checks.
