Central repository of cases

## User story
As an instructor user,
I want to be able to view all health case studies available across BC post-secondary institutions
So that I am aware of all the resources available for me to teach my students and so that I can prevent redundancy in my work.

## Description
Published case studies should be easily accessible to instructors who wish to use them from within the EdEHR. This feature is a page in the EdEHR where all cases can be viewed.

## Expected behaviour
- All published cases will appear with an organized coding convention
- Filter ability
- TBD

The issue names no files, tests, or entry points. Start by clarifying the coding convention, filter requirements, and the meaning of “TBD”; done means a page in the EdEHR exposes all published cases across BC post-secondary institutions and supports the agreed filtering.
