What this PR solves / how to test

This PR rewrites the fixtures/dev-env tests as e2e tests. Whereas the former were written when only the ProxyController had been implemented and therefore faked all other events, these new tests assume a full implementation.

The steps in each test are identical but have been rewritten for e2e usage. Notable difference: the script contents is written to disk instead of passing it via config because config.entrypoint.contents has been descoped for now.
