chore: import fixes to fix e2e tests

[toddbaert]

Both the server and client e2e tests run fine in the CI, but in some local scenarios the "deep imports" we used were causing issues with module resolution.

I've updated the e2e test to always import from the "top level" instead of the /src sub-directory in the test suite.

@jamescarr I'm not 100% sure this will fix your issue locally (I wasn't able to reproduce it) but it might.
