[WIP] API Integration Testing

Goal is to ensure that Departure can do everything Departure needs to do using the API.

Use unit testing framework, ideally mock database but can just reset database with scripts for now.

These workflows must be possible even starting from nothing but a kit id or nothing but a login JWT, sometimes differentiating the required integration tests from unit tests of individual api functions.
