CR: Retrieve and use email address from BCSC or BCeID during application

## Use Case

As an Applicant, I want the email address associated with my BCeID or BCSC to be automatically used in my initial application or renewal application
So that I am not required to manually enter my email address.

As an Examiner, I want the email address associated with the Applicant's BCeID or BCSC to be automatically used in any initial application or renewal application
So that the Applicant is not required to manually enter a potentially incorrect email address.
