Fix production issues: add matplotlib dep, fix get_db calls, resolve ESLint

- Add matplotlib>=3.7.0 to requirements-podcast.txt (B-roll requires it)
- Fix research.py and exa_provider.py using get_session_for_user() instead of broken Depends(get_db)
- Fix BrollInfoPanel.tsx: call useScriptEditor hook unconditionally
- Add debug logging to avatar endpoint for troubleshooting
