Implement `useQuery` hook

[269652]

We need a way to directly query the database in order to obtain a list of states for a given scope and key. At the moment you need to use arrays to keep track of "lists". While this makes sense for finite lists, it doesn't make sense for lists with an indefinite / growing length, such as posts in a forum.

If we implement a reactive useQuery hook, we can directly pass client side paging props to the database and return a reactive / live query to the server which contains all states for the requested scope.

This also mitigates the need to reflect changes to a single post in the list itself such as approving a post as the useQuery already obtains all the needed information and rerenders the component if a state has been added to the lists.
