Description

See Cargo.toml on what lints are now enabled. They apply to all workspace members.

Some lints we want to enable in the future, but for now I'm ignoring them, as the PR is big enough already with the easy ones.
E.g. we need to think about many possible number truncations.

I suggest reviewing the commits one by one. Some lints have been auto-corrected (--fix), some manually.
