Add attended runtime-lease remint helper for the expired ESO token

The 768h orphan token in external-secrets/openbao-audit-core-eso-token
expired at 2026-09-14T10:23Z and ClusterSecretStore lookup-self is 403,
so ESO cannot mint database/creds/audit-core-runtime. Recreate the
Kubernetes Secret without last-applied-configuration so the token is
not stored in annotation metadata.
