Replace black with ruff and fix code formatting

[z-a-f]

This replaces the black with ruff as linter and formatter:

• Ruff is faster and more accurate
• There are more rules enabled in Ruff than in Black
• Ruff is more configurable and has more options

Warning

This will cause a lot of changes to the codebase.

Note

Code changes (beyond ruff enablement) are automated refactoring by linters

The event loop scope for asynchronous fixtures will default to the fixture caching scope. Future versions of pytest-asyncio will default the loop scope for asynchronous fixtures to function scope. Set the default fixture loop scope explicitly in order to avoid unexpected behavior in the future. Valid fixture loop scopes are: "function", "class", "module", "package", "session"
