test: migrate custom resources test to setupHarperWithFixture

Replace startHarper + installAppComponent + readFileSync with
setupHarperWithFixture. Adds a readiness poll for /WorkItem/ after
startup since the route registration completes slightly after
startHarper resolves when a component is pre-loaded at boot time.
