Address review: keep the /reference/python URL, tighten the generated intro

Rename the generated page to reference/python.mdx so the URL already
published on the website stays valid, and redirect the short-lived
/reference/python-api to it instead. Split the conventions into one
paragraph per subject, move the Session.call and ToolError sentences under
the Session heading, and stop rendering the package's module docstring since
the guide is already linked as the practical documentation.
