Use quarterdeck user id as member id

[pdeziel]

Scope of changes

This updates the Tenant register method so that the Quarterdeck user ID is used as the member ID. This fixes an issue with the Member Detail endpoint that the frontend was experiencing because it was expecting the member ID to be in the user claims.

Fixes SC-14814
