Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Avoid propTypes and defaultProps in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Avoid using ../ in import paths. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'

@ChrisChV Overall it looks good.

The add sidebar even works in library sourced units, we should probably disable/hide add button and also have a check in add sidebar to disallow adding components.

[navinkarkera]

@ChrisChV We need to come up with better filter here, it is displaying units, subsections, sections and other components from courses including course blocks.

Suggested change

	extraFilter={['NOT block_type = "unit"', 'NOT block_type = "section"', 'NOT block_type = "subsection"']}
	extraFilter={['type = "library_block"']}

Above change works but we need to test it a bit more.

[navinkarkera]

@ChrisChV Looks good.

[bradenmacdonald]

LGTM! Please just make the component colors more DRY by refactoring them to use CSS variables (not SCSS variables) and this is good to go as far as I'm concerned.

Thanks for those changes! ✅
