Grant vault deployer access to import + manage the rancher engine

The rancher token secrets engine is registered ('imported') into the catalog by terraform-vault (sys/plugins/catalog, sudo-protected) and configured via the ranchervaultsecret provider, so the deployer needs catalog access plus write on the engine's config/service-accounts/roles paths. Without this, apply 403s on plugin registration and on rancher/* writes. - Add policies/rancher/admin.yaml granting the tf_vault approle and the woodpecker_terraform_vault k8s role: catalog sudo on the plugin, and manage on rancher/{config,service-accounts,roles}.
Register + mount the GPG secrets engine at gpg/ (#87 )
