add user account email verificiation (#977)

* add user account email verificiation

includes server and client code to:

* enable verificationRequired via custom config
* send verification email with registration
* ask for verification email
* verify via email
* prevent login if not verified and required
* conditional client links to ask for new verification email

* allow login for verified=null

these are users created when verification not required
should still be able to login when verification is enabled

* refactor email verifcation pr

* change naming from verified to emailVerified
* change naming from askVerifyEmail to askSendVerifyEmail
* undo unrelated automatic prettier formatting on api/config
* use redirectService for home
* remove redundant success notification on email verified
