feat: Add Render.com deployment support with production data

Render Configuration:
- render.yaml for declarative deployment
- requirements-dashboard.txt (lightweight deps for cloud)
- Updated .streamlit/config.toml for production
- Updated app.py to auto-detect production vs local data

Production Data:
- Added data/production/test-07/ with 30 real call analyses
- Updated .gitignore to allow data/production/

Documentation:
- Added Render.com section to DEPLOYMENT.md with step-by-step guide
