test: adds setup for mock-service-worker (#127)

* test: add msw and basic handlers for a few types

* test: add mock data for a basic workflow execution

* test: fixing/removing tests after adding msw

* test: throw on unexpected requests to msw

* fix: upgrade TS to fix error and cleanup resulting errors
