Subject: [PATCH] Update loading spinner status (#28177)

* Update test for the loading spinner component

* Create a story for the loading spinner component

* Move role and use CSS for spacing instead

* Add a classname prop

* Reuse LoadingSpinner

* Use OLSpinner instead of Spinner

* Use data-testid since status role was moved

* Wait for journals to load

* Use `isLoading` prop instead and fix the button's height

* Use `isLoading` prop instead

* Use LoadingSpinner instead and remove spacing

* Update test for the loading spinner component

* Use `isLoading` prop instead

* Add aria-describedby to layout button for processing state

* Replace `spinner` to `ol-spinner`

* Scope status

* Remove redundant `div.loading`
