feat(frontend): Module consolidation for some test modules and reduces errors from unsupported API calls

[cptran777]

This PR reflects recent work taking place internally. It consolidates some of the testing modules for the frontend, which should help improve build times and create a more manageable testing suite. It also resolves some issues raised by the open source community in response to recent changes. There are also some "behind-the-scenes" kind of changes going in that help us resolve some challenges in creating a smooth, semi-automated pipeline between internal and open source development in order to rollout changes more quickly.

Issues resolved:

• Does the frontend page no longer display the dataset description #1823
• Social function issues introduced by the latest version of the frontend #1824

Testing Done:

gradlew build successful
BUILD SUCCESSFUL in 11m 36s
227 actionable tasks: 227 executed

Ran docker images and tested changes to ensure that application builds and behaves as expected
