Lint: Add tailwind linter (#5984)

## Summary

Adds the [tailwind lint
plugin](https://github.com/francoismassart/eslint-plugin-tailwindcss/?tab=readme-ov-file#eslint-plugin-tailwindcss)
and fixes the currently fixable rules ([v4 is still in
beta](https://github.com/francoismassart/eslint-plugin-tailwindcss/?tab=readme-ov-file#about-tailwind-css-4-support)).

## Changes

- **What**: Enforces things like consistent class order, and eventually
can prohibit extra classes that could be utilities instead
- **Dependencies**: The plugin and its types
