This keeps the old "react-app" directory in its existing location (to make
it easier to merge changes from the main branch), but separates it from the
npm workspaces setup. Thus it now needs to be npm-installed/built/linted
separately. This is a bit hacky, but should only be needed temporarily,
until the old UI can be removed.

This updates React, TypeScript, and some other node packages (but not
everything).
A couple of notes:
- `enzyme-adapter-react-16` does not have a React 17 equivalent yet, so I
switched to the fork `@wojtekmaj/enzyme-adapter-react-17`
- A bunch of tests are still failing because I think in the enzyme testing
environment, a browser API (`ResizeObserver`) is missing, and maybe for other
reasons. This needs to be explored + fixed.
- The TypeScript update introduced more stringent rules, which required fixing
up a bunch of pieces of code a bit.
- The `use-media` package doesn't work with React 17 yet, so I just built our
own minimal `useMedia` hook instead (just a couple of lines).
- I commented out part of the code in `withStartingIndicator.tsx` because it
fails the now-stricter lint checks. It needs to be fixed (and not commented
out).
