Create Integration Test Foundation

[pauljamescleary]

Create integration tests that stage data in H2 where necessary and hit the API endpoints.

We would like to avoid specific unit tests except for our core business rules. Most tests should be possible by staging data in the database and hitting the APIs directly.

Once the foundation is setup, we can create issues for testing the endpoints.

Also, should add test coverage here as well, possibly adding some minimum test coverage check.

Closing this as it should be re-worded as to the intent. Will open a new one once the rest of the features are there.
