Description

This is a preview PR to show what the diff would look like if we wanted to switch from using eslint checks to oxmft as our code formatter.

There are rather a lot of changes, because oxfmt is designed to copy prettier, not eslint's formatter. Since we weren't using prettier, it results in quite a lot of changes. Changing the resulting format is not possible as neither prettier nor oxfmt support many options (on purpose).

The main philosophical difference is that prettier/oxfmt always put things on one line if it's possible without going over the line length, whereas eslint allowed you to "choose" to use a multi-line format or not for each thing, at your discretion.

Based on this diff, I am not recommending adopting oxfmt at this time, as it creates too large of diff and is too prescriptive. I think a better approach will be to use ESlint Stylistic only for code formatting, and oxlint for linting.

useToggle,

import { ActionRow, Card, Form, Icon, IconButton, ModalPopup, useToggle } from '@openedx/paragon';

I don't like that oxfmt forces imports to be on one line, if they could possibly fit on one line, even if the author chose to have them on individual lines.

Another example of forcing one line when the author preferred multiple lines for readability.
