Title: Show a "Signing in" message after the user selects an email from the email picker or successfully authenticates

@ryanfeeley already approves these changes from a UX perspective.

* Give the same signin notice for both primary and secondary sign ins
* Replace primary_user_verified.ejs with signing_in.ejs

An ephemeral instance is re-used - primary-verified.personatest.org

fixes #3708
