Return SMTP response in status

[loneil]

Description

Add the smtp response to the Status calls to facilitate troubleshooting.
https://apps.nrs.gov.bc.ca/int/jira/browse/SHOWCASE-1151

This field is public.message.sendResult in the DB and is populated when the message is set to completed.

Since this is an additive change to a status endpoint I don't think we need to worry about any API versioning on this change.

Leaving draft. If reviews look good will set up some test data before merge on monday.

Add badge (#62) and npm audit fix as well
