[console] Test run with scout / playwright - move some api and functional tests

[mattkime]

The scout / playwright test framework has a number of advantages - better developer ux, faster test execution to name a few. I'll take it on a test drive by moving some tests over. I'll start with api integration tests and continue with some functional tests.
