Enhance error states on form fields

Medium priority

When validating form fields today, we include an error state on a required field that the user did not complete. It's not always obvious which fields are not filled out and we force the user to scroll up and find it. This issue is proposing to:

1. Automatically scroll the form up to see the required fields that need to be completed (if there are many, scroll to the first one)
2. Apply animation to a field so it appears to shake once it has been scrolled to (here's a prototype of an example)
