Improve dev experience a bit, by updating our tooling and the packages we use

Check List

• Use craco #431

• go through the todos and see what can be done and do it if possible #486
• forbid using relative imports across the repo #492

@ZibanPirate I was thinking perhaps it's the time to use relative imports as well in the mobile codebase.

Old:

import { ErrorBoundary } from "../../../components/error-boundary";

New:

import { ErrorBoundary } from "components/error-boundary";

our first successful milestone is now closed yay 🎊
