Upgrading ruff to v0.16

I’ve looked into upgrading ruff from our current version 0.14.14 to the newest 0.16.1; turns out that ruff now enables _a lot_ more rules by default, as it finds 1137 errors (sic) in our codebase. I haven’t had time to go through all of this yet; I assume that some of this will be sensible while we may want to exclude other rules.

A common one is **I001: unsorted-imports**, which expects imports at the top of a Python file to be alphabetically sorted. How do we feel about this? In principle, I do kind of like this as it creates more consistency, though it does create a ton of changed files (176).

I’ll paste the full list of new error codes in our repo below, and will update this once I’ve had time to take a closer look.
