Backend for campaign reports

[batebobo]

Summary

Implements #368

Created CRUD endpoints for campaign reports. They are part of a separate module called campaign-report, but the controller is under the campaign base route.

New entities:

• CampaignReport
• CampaignReportFile

Both entities support soft delete and have an owner (uploader).

Screenshot of how the new routes look like:
