Refactor Argo CD application configuration to adopt a multi-source approach for noble-platform, removing Helm chart definitions from kustomization.yaml. Update noble-platform.yaml to directly reference Helm chart sources and clarify documentation in README.md and apps/README.md regarding the new structure and resource representation in the UI.
