Add system namespace filtering

- Add configuration to exclude system namespaces by default
- Add UI checkbox to include system namespaces when needed
- Update API endpoints to accept include_system_namespaces parameter
- Update Kubernetes client to apply namespace filtering
- Update ConfigMap and deployment with new environment variables
- Fix Dockerfile to install dependencies globally
- Test functionality with both filtered and unfiltered results
