Display Email Address in Dashboard?

[nelsonic]

At present the dashboard displays the status of emails: https://dwylmail.herokuapp.com

This is much better than zero visibility. But it's not actionable.
We need to be able to click on an item to see the email address so we know exactly what went wrong.
In order to view an email address we need Auth to ensure privacy.

• Enable Auth for the Email App once the DWYL_API_KEY feature is shipped EPIC: AUTH_API_KEY How to Run the App with a Single Environment Variable auth#42
• Make the each row of the dashboard clickable.
• Render the "show" view including the decrypted email address if the requestor is authorised to see it.
