Email verification and change flows

[pfrazee]

• Adds email verification flow
• Adds email change flow
• Adds a reminder on app load to verify email if not verified. Reminder only shows once a day and shards the users into 2 days of the week to get it, to avoid nagging too much and to avoid everybody running the flow all at once.

LGTM

Nit on the auto* attributes.

Could probably clarify the error copy when trying to change your email prior to having first verified the current email. Rn it just says confirmation token required, but really it's You must first verify your current email before changing it.
