Improve visibility of Python public APIs to type checkers

[abey79]

What

• Closes Python autocomplete worse since 0.16 #6459

#6117 removed many __all__ statements, which cause problem for type checkers when using our public APIs (rr.* and rr.blueprint.*). This PR fixes this by using the from X import Y as Y pattern, which is easier to maintain than __all__.

This required a ruff setting change, which rippled into additional (arguably good) formatting changes.
