chore: migrate backend from Azure Web App to Container App

- Replace soc-langgraph Web App with Azure Container App (soc-cae environment)
- New URL: soc-langgraph.victorioussand-69befc84.southeastasia.azurecontainerapps.io
- Update deploy-langgraph.yml: Web App restart -> az containerapp update --image
- Update deploy-langgraph-ui.yml: VITE_LANGGRAPH_URL to Container App URL
- Container App: min 1 replica, max 3, CPU 1.0, Memory 2Gi, port 8080
- Update CLAUDE.md architecture and deployment docs
