  Spare uses OAuth2 client-credentials. A client presents its API credentials
  (client id + client secret) to the Authentication API Token endpoint and
  receives a signed JWT access token plus a refresh token. The access token is a
  short-lived bearer token supplied on every protected request in the
  Authorization header as `Bearer <JWT>`; when it expires the refresh token is
  exchanged for a new access token via the Refresh endpoint. Token, payload and
  webhook (x-signature) signatures are verified against the tenant JWKS published
  by the Authentication API. API keys are provisioned in the Dashboard as an
  ECC secp256r1 (prime256v1) PKCS#8 key pair for request/message signing, with an
  optional IP allow-list. Each tenant (Bahrain, KSA, UAE) is a separate host, so
  tokens are tenant-scoped.
