fix: use enterprise-pull-secret and .Chart.AppVersion for image tag

- Set global.imagePullSecrets to enterprise-pull-secret in values.yaml
  (EC v3 creates this secret; ImagePullSecretName returns wrong name)
- Set image.tag to empty string so .Chart.AppVersion fallback is used
- Remove global.imagePullSecrets override from helmchart.yaml
