chore(server): improve server tests (#9958)

I left these server tests in a not-so-great state after
#9948. Got around to improving
them today with @Josh-Walker-GM. Want to add more, but this covers the
new features I added, mainly the configuration around the web and api
ports and hosts.

I've tried to add this to CI before but they were flakey. I feel like
they're less flakey now and Josh helped me with retry logic. So I think
we could try adding them to CI again and see how it goes.

You can run these tests after building the framework. `cd` into
`tasks/server-tests` and run `yarn vitest run`. The tests also log the
bins they're using and you can run those verbatim.

I split the tests up into separate files mainly because the terminal
becomes unreadable if they're all in the same one.
