What Should Reviewers Watch For?

If you're reviewing this PR, please check for these things in particular:

Validation

1. Check out the PR and spin up a local bb2 server
2. Passing tests not required since some tests break due to the changes
3. Create a user e.g. U001, and add an app under the user e.g. MyApp001
4. Use the swagger UI to authorize e.g. BBUser00000
5. Upon authorize success, do a FHIR query, e.g. GET Coverage with resource id
6. For BBUser00000, there is a coverage with ID: part-b--10000010254618
7. { "resource": { "resourceType": "Coverage", "id": "part-b--10000010254618", "meta": { "lastUpdated": "2023-06-14T18:17:07.293+00:00", "profile": [ "http://hl7.org/fhir/us/carin-bb/StructureDefinition/C4BB-Coverage" ] }, "extension": [ {
8. Do a GET Coverage with resource_id like shown below:

10. Should see response: Coverage
11.

12. Now change the resource_id value to: part-b_______--10000010254618, a malformed coverage ID, and execute the GET Coverage, you will get a OperationOutcome resource indicating a 400 situation : Bad parameters

Above demonstrates the new behavior of FHIR endpoints passthrough the FHIR OperationOutcome to the API caller
