Tests are successful. We are removing the Cypress test. It appears to be in a stalled state, but going to the "Actions" tab on the project shows that the entire workflow was processed successfully.

Making this a draft temporarily. Two issues in the most recent commit:

• eslint errors - FIXED locally
• System banner test now fails with new React mount
  • May need to create different mounts for React and simple components or need to figure out why MemoryRouter is messing up the banner

Cancelling this for now while other work is prioritized. Will re-review this once Cypress component testing is ready to be implemented.
