Update Python version requirements and fix compatibility issues
- Bump minimum Python version from 3.11 to 3.13 across all apps - Add Python 3.11-3.13 test matrix to CLI workflow - Document Python 3.11+ requirement in .env.example - Fix Starlette Broadcast removal with in-process fallback implementation - Add _InProcessBroadcast class for tests when Starlette Broadcast is unavailable - Refactor API key validators to read live settings instead of cached values - Update database models with explicit
