run pre-commit on all files (#1789)

pre-commit.ci has been disabled for a while.
This PR ensures that all the files has been validated/formatted by pre-commit, to avoid spurious diffs in subsequent PRs.

During the process, ruff broke the code because it removed an "unused" import which was actually used.
A linter which breaks my code is a linter which I cannot trust, so I just removed it. I re-enabled isort instead.
