As a guest, I want to be able to register a new account

[MGZero]

Note: This flow should not be available to logged in users.

A guest user should be able to click the registration button and be brought to the terms of service page.
Upon clicking next, the user should be brought to the registration page from #10.
After filling out all required fields and passing recaptcha, the register button should become enabled.
Clicking the register button will call the register endpoint which will check required fields, validate the data, and run rule checks.
If an error is triggered by one of the above checks, a 422 will be returned (the error messages will be handled in a follow-up story).
If required fields are missed, they should highlight in the error color.
When the user successfully registers, they will see a success message that tells them a validation email has been dispatched.
The user should then be returned to the home page.
