When ReportIncidentDeveloperMode is on, return the email contents with the API response. The caller (ReportIncidentDialog.vue) should log this to the browser console. The idea is that a user can see what the email would look like, for QA and testing purposes.
Acceptance criteria:
- submitting a valid report form shows me the email contents in the browser console when ReportIncidentDeveloperMode is true
- email contents are included in the API repsonse when ReportIncidentDeveloperMode is true
