refactor: use the traced file copy from OpenNext

[vicb]

fixes #251
relates to #14

Before this PR, the Next compiled output was copied to .open-next/.next and some files were used/patched from there.

This PR makes sure we always use the files from .open-next/.server-functions/<fnName> instead.

This allows to simplify a lot of the config object that was used before.

Oops, I merged @james-elicx PR into this one (I forgot it was based on this branch).

@dario-piotrowicz you can review the first commit only, thanks!

Looks very promising! 😄 🥳

I'm halfway through my review, just leaving a partial review 🙂

Nit: I didn't comment on them since there are quite a few, but you're introducing a bunch of joins that are inconsistent with your convention
