fix(bp-external-secrets): gate ClusterSecretStore on CRD presence + drop delete-policy (#337)

The chart's post-install hook was failing on otech.omani.works:
  failed post-install: unable to build kubernetes object for deleting hook
  bp-external-secrets/templates/clustersecretstore-vault-region1.yaml:
  resource mapping not found for kind ClusterSecretStore in version
  external-secrets.io/v1beta1
Two corrections:
1. Capabilities-gate the entire template — don't render unless the
   ClusterSecretStore CRD is registered (it ships in via the upstream
   ESO subchart but isn't live on first install)
2. Remove 'before-hook-creation' delete-policy (was the actual trigger
   for the 'deleting hook' failure path)
Bumped 1.0.0 → 1.0.1.
