fix(e2e): use correct ConfigMap name in E2E tests

Controller creates ConfigMaps as {name}-config (see reconcile_configmap.go:48),
but the test was looking for {name} without the suffix. Traced by reading
controller logs which showed StatefulSet and pod were created but ConfigMap
check failed after 120s — confirmed configmap name mismatch by reading
reconcile_configmap.go and reconcile_statefulset.go (both use node.Name+"-config").

Context: spent ~30min analyzing CI logs and controller reconcile order to
identify this naming mismatch. ConfigMap is created first in reconcile order,
StatefulSet references it as {name}-config, test was checking wrong name.
