- AuthFailedAt is set when a refreshToken is not valid and an
accessToken can't be generated, meaning it will need a manual action

- Calendar/messaging jobs should not be executed if authFailedAt is not
null.

SyncExternalId should be renamed because this won't always represent an

sync. Also we think external is a bit redundant so we are removing it.
Note: this field is not used by the front-end (and will probably never
be)
