chore: remove eslint.config.js

ESLint cannot support our preferred code style for backend without
writing custom plugins. On frontend, we already decided ESLint wasn't a
good fit several months ago. This commit removes the eslint config to
avoid other developer's editors making unwanted whitespace changes.

In backend, we use spaces within control structure parens. This really
does make the code easier to read. In the future, maybe we'll write our
own linter.
