[Redux] Refactor Redux into using RTK + React Redux and expand Redux into one site wide store

[Michaeldremy]

We are using the classic version of Redux and the Modern way of writing redux. It's time to get rid of the old and in with the new!

@reduxjs/toolkit + react-redux is the modern take on writing redux. Look into migrating code/versions into using @reduxjs/toolkit + react-redux.

Additionally it is better to have one large store rather then multiple stores as it improves performance. Only under specific circumstances does the store need to be broken into smaller ones.
