FIX(argocd): use control-plane nodeSelector

- Change nodeSelector from master to control-plane
- K8s nodes have control-plane: "true" label
- Fix pod scheduling failure

FIX(argocd): use hostname instead of hosts for ingress

- Change from hosts array to hostname string
- Change tls from array to boolean
- Matches argo-cd Helm chart expected format

FIX(argocd): resolve SharedResourceWarning

- Change from including argocd/ folder to argocd/argocd.yaml only
- Namespace and webhook-ingress now managed by argocd app only
- Prevents duplicate resource management between platform and argocd
