Format Python scripts across the repository (#42109)

## Why

The root Python formatting pass only covered `scripts/`, leaving Python utilities elsewhere in the repository outside `just fmt` and `just fmt-check`.

## What changed

- Run the scripts Ruff formatter from the repository root.
- Exclude `sdk/python`, which has its own formatter pass, and `codex-rs/vendor`.
- Apply Ruff formatting to the newly covered Python files and update the formatter coverage test.
