The App.tsx had a bunch of separate useState calls which would
cause unneccesary re-renders of the entire app. This became
apparent after adding the global progress bar, since it caused
even more re-renders to the point of being unusable.
This simplifies our codebase greatly by
only having a single stack navigator and
a single drawer navigator. Previously we had
a stack navigator for every main page on the drawer.
