OAuth 2.0 client-credentials token issuance for machine integrations
Standard RFC 6749 token endpoint. The client authenticates with HTTP Basic (preferred) or body client_id/client_secret parameters and receives a short-lived signed JWT bearer token. Responses use OAuth error semantics and are never stored.
