Currently, the project doesn't have working test functionality. We want to be able to use Jest and React Testing Library to add unit and integration tests to the app. However, there are a few build errors such as a compatibility issue between MUI and React 18.
This PR fixes build errors, and then sets up and configures Jest and React Testing Library, along with adding some basic tests to ensure that the environment works properly.
