WS-1168: Email modal on QA fail, QA abandon, and capability close
Made an email modal that can be used to send any email template with cc addresses and custom text. This is used on the QA fail, QA abandon, and capability close buttons. It POSTs to the notification service with a JSON of all required info.
This also includes WS-1615 to add a button to close a failed capability. This involved making a new capability request endpoint to seal the request.
