@1aurabrown => Add support for registration flow up to the zip VC

This finishes up the registration process of the app, at least to the point of their being all the data internally in order to then start creating accounts and registering cards.

* Removed tests for VCs that don't exist anymore
* Makes tests green, at the expense of some existing tests. Will clean this up sometime on slow time.
I think you can fully delete this and also for the bid confirmation phone number text field
