Move security scan status strings to frontend

This moves the status strings from the Rails ConfigurationPresenter to Vue components in the frontend.

1. The first sets up pinning tests to record the current behaviour.
2. The second implements the changes and updates the pinning tests accordingly (if you view this commit directly, it's best to view it with Show whitespace changes unchecked).
3. The final commit removes the pinning tests.
