Changes

Use mock service worker (msw) in tests to more closely replicate a real environment, mocking at the network level instead of at the API level.

This gives greater visibility into tests that are not properly isolated, avoids issues specific to fetch or whichever request library is being used, and could also be used for e2e testing in future.

Another motivation behind the change is the fact that fetch-mock hasn't been updated in about 2 years and uses a number of deprecated packages including querystring which will no longer receive updates for vulnerabilities.
