Add machine relationship to operator report email alerts

- Query AssetRelationship to find if PC has a machine relationship
- Subject line now shows: "Operator Issue Report: HOSTNAME (Machine #6906)"
- Email body includes machine name and number as clickable link
- Machine info only appears if relationship exists
