Enhancement: Add Student CSFA Accomodation Section to Student Application Endpoint Response

[klondikemarlen]

Relates to icefoganalytics/student-financial-aid#2
Fixes #30

Context

As part of the "view submitted applications and their current status" project, this task covers returning the student CSFA accommodations data.

Implementation

Decide to standardize spelling in back end, because I don't want to propagate the typos. I'd rather require the front-end be fixed to match.

Data Format

{
  "id": "some-application-id",
  "csfaAccommodation": {
    "accommodations": [
      {
        ...
      }
   ],
  },
}

Testing Instructions

1. Boot the sfa-client repo via API_PORT=3100 dev up
2. Boot the student-financial-aid front- and back-ends.
3. Log in to the app at http://localhost:8080/
4. Go to http://localhost:3000/api/portal/students/1/applications/2198 and you will see an example of some accommodations.
