Reformat code with 'ruff format'

[felixfontein]

SUMMARY

Will likely merge this on ~Saturday.

For that, I will:

1. Recreate the first commit from current state of main;
2. Update second commit so first commit is mentioned in .git-blame-ignore-revs;
3. Merge with rebase so that two commits end up in main.

This PR mainly shows how the result will look like.

Man, I will just trust the code. No way I can review 1000+ files before Sunday and keep my marriage at the same time.

I didn't expect you (or anyone else) to review everything :D (Also some things will change when I have to re-create the first commit.) The 'interesting' part is the second commit: ed71c3e

(Some manual post-processing is needed, but I will only do that when it's clear I don't have to re-do the work...)

The CI error is unrelated.
