no issue Reduces likelihood of seeing the "Loading editor..." state when accessing the editor by fetching the editor module in the background after login. - added `koenig` service - `.resource` getter for returning a React suspense resource object to reduce duplication across main editor and HTML input components - `.fetch()` method that fetches the Koenig module, avoids concurrent or repeated fetches by utilising an internal `._fetchTask` ember-concurrency task - updated Koenig components to use the `koenig` service and associated resource for fetching the module - required setting up `editorResource` inside the component's class and passing it in as a prop to the suspense-aware components as we need access to Ember's dependency injection available in the class - added `koenig.fetch()` call to our post-login code in the `session` service so the fetch is started before the editor is accessed
