Modernize Python dependencies to 2025 standards

- Update Python 3.6 → 3.11 in runtime.txt
- Create pyproject.toml with modern project metadata
- Update all plotting libraries to latest versions:
  - plotly 4.10 → 5.24+ (no authentication needed)
  - plotnine → 0.13+ (better ggplot2 compatibility)
  - altair → 5.0+ (major version bump)
  - statsmodels 0.11 → 0.14+ (security fixes)
  - seaborn, pandas, matplotlib to latest
- Remove deprecated packages:
  - altair-saver (use native rendering)
  - chart-studio (not needed with plotly v5)
  - duplicate selenium entry
- Update rpy2 to 3.5+ for Python 3.11 compatibility
