Code Review

This PR bumps the Snyk-mandated ipython floor from >=9.14.1 to >=9.15.0 across all three requirements files (base.txt, local.txt, production.txt). The change is purely a minimum-version floor raise on an indirect dependency pinned for security — no logic or API changes.

Assessment: nothing to act on.

A few observations for completeness:

• Consistency ✓ — all three requirements files are updated identically.
• Pin format ✓ — the >= constraint is unchanged; the new floor correctly excludes the older version while leaving room for future patch releases.
• Scope ✓ — ipython is not imported anywhere in the application code (one comment reference in config/graphql_auth0_auth/settings.py is unrelated). The pin exists solely to satisfy Snyk's transitive vulnerability scan.
• 9.15.0 changes — the release includes minor bugfixes (kitty graphics crash prevention, %run glob-quoting fix, ANSI stripping in Sphinx output). Nothing that affects this project's runtime behaviour.

Safe to merge.
