[Feature]: Expand ruff checkers

Why is this issue important?

ruff does a good job of checking and auto-fixing python to be more correct and more consistent.

This project is just using the default 4 checkers, but there are dozens. One I like is UP, like pyupgrade, that updates all the code to be most idiomatic for our chosen python version (e.g., python 3.12). As an example, I noticed a bunch of Optional[str] type hints, which is now str | None.

Another which is aggressive but helpful is "Q" just to make sure all quotes are the same (default: double quotes). This is the kind of tiny stuff that it's good to just have a machine do.

In combination with pre-commit, ruff can auto-rewrite our code safely and with no effort as we push stuff up.

Current State

Default checkers.

Expected State

More checkers.

Implementation Plan

Add more checkers to the tool.ruff.lint section of pyproject.toml in python.
If there are errors that are not auto-fixed, add them to the ignore list.
For those checkers with only a few errors, try removing them from the ignore list and fixing them by hand.

For example, just adding "I", "UP", and "SIM" on my branch produced this:

$ ruff check --fix
src/functions/create_archive.py:88:5: SIM117 Use a single `with` statement with multiple contexts instead of nested `with` statements
src/functions/generate_treasury_report.py:457:9: SIM118 Use `key in dict` instead of `key in dict.keys()`

tests/conftest.py:231:12: SIM115 Use context handler for opening files
Found 318 errors (312 fixed, 6 remaining).
No fixes available (2 hidden fixes can be enabled with the `--unsafe-fixes` option).

$ git diff | wc -l
    2121

A lot of it is just re-ordering imports, and using a newer style of type hinting.

This is stuff we'd like a computer to keep straight for us.
