Support for React 19

[michaelhays]

Creating this issue to track box-ui-elements support for React 19.

I upgraded react and react-dom to the latest RC versions (19.0.0-rc-77b637d6-20241016 at the time of this writing), and I'm no longer able to import from box-ui-elements, due to this error:

• findDOMNode has been removed from React
  • https://github.com/facebook/react/issues/28926

I'm finding some other errors testing with the Next.js 15 RC, but I'm not sure if these are strictly React 19 related.

Turbopack (bun next dev --turbo)

• The export default was not found in module [project]/node_modules/tabbable/dist/index.esm.js
  • Fixed by changing import tabbable from 'tabbable' to import { tabbable } from 'tabbable'
• /node_modules/box-ui-elements/es/components/toggle/Toggle.scss.css:33:9 Parsing css source code failed
  • Maybe caused by trying to parse SCSS as CSS?

Webpack (bun next build)

• Module not found: Can't resolve 'moment' in '/home/michael/projects/sirvatus/node_modules/pikaday'

Just a heads up, Next.js 15 was just released as stable, and requires React 19 for the app router.
