chore: remove fastapi status and add ruff rule

[Stellatsuu]

Closes: #823

Question:
Ruff is currently ran on diracx related code only:

[tool.ruff]
src = ["diracx-*/src", "diracx-*/tests"]

For this issue, I had to change some parts of code related to gubbins, should we also add it to ruff or not?

Thanks @Stellatsuu, is that ready to be reviewed? If so please mark it a ready for review 🙂

[Stellatsuu]

It is ready @aldbr, I was waiting for the CI to pass before removing the draft. Could you please respond to my question in the PR description before merging anything? In case I need to do some changes related to that

Yes please also apply your changes to gubbins and add the ruff rules to the pyproject.toml there
