Setup effective(?) linting

Setup more stringent linting rules, including sorting import statements

When does the linter run? And do builds automatically fail if the linter fails?

My strong preference is having it run automatically with, at minimum, production builds and failing the build. I'm personally a fan of having it run with dev builds as well, but I know that's more contentious as it slows down prototype-style development.

Linting runs as part of the yarn lint or yarn build tasks. It shouldn't run during yarn dev, but it's recommended that your IDE know about lint rules (Visual Studio Code with the ESLint extension should work).

There's a GitHub action that should block commits to main or merging PRs with failing builds.
