Improve visibility of Python public APIs to type checkers (rerun-io#6462

)

### What

- Closes rerun-io#6459 

rerun-io#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.
