Save OAuth 2.0 client-credentials for an agent

Store a machine-to-machine OAuth 2.0 client-credentials configuration (RFC 6749 §4.4) for this agent. The SDK exchanges at the token endpoint before every call and refreshes on 401. client_secret may be a $ENV:VAR_NAME reference — the SDK resolves at exchange time, the server stores it as written (encrypted uniformly). Requires authentication and ownership.
