Title: Usability updates to the signin page.

* If the user enters an unknown secondary email, redirect them to the /signup page.
* If the user arrives with a known secondary email in storage, show the password field.

This is part of the fix for #2120, the signup page needs to be given the same treatment.

The page load could use some work, but I am going for an incremental improvement here.
