fix: use namePrefix-compatible name for ClusterRole

[lukacsi]

Fixes #7

Fix

Rename the ClusterRole source from manager-role to -role, matching the convention used by all other RBAC resources (-rolebinding, -account, -leader-election-role). Also update the roleRef in the ClusterRoleBinding to -role.

With namePrefix: dcontroller, kustomize now produces dcontroller-role for both.

Commits

1. fix: Rename source names in config/rbac/role.yaml and role_binding.yaml
2. chore: Regenerate chart/helm/templates/all.yaml via kustomize build (also picks up other pending source changes)

Verification

$ kustomize build config/helm-base | grep "name:.*role"
  name: dcontroller-leader-election-role
  name: dcontroller-role
  name: dcontroller-leader-election-rolebinding
  name: dcontroller-leader-election-role
  name: dcontroller-rolebinding
  name: dcontroller-role
