When jwt.filer_signing.key is set, the filer's IamGrpcServer requires a Bearer token on every IAM RPC. The shell's s3.* IAM commands dialed without that header and failed with Unauthenticated. Route them through a small helper that mints a token from the same key viper-loaded from security.toml and appends it as outgoing metadata, matching the credential grpc_store pattern.
