fix: complete AG2 migration by replacing remaining pyautogen references

- Replace pyautogen==0.2.29 with ag2==0.2.29 in autogen extra dependency
- Update integration test documentation to reference ag2 instead of pyautogen
- Fix comment referencing pyautogen numpy conflicts

This completes the AG2 migration that was started in PR #1156, ensuring
backward compatibility while moving to the new ag2 library.
