Submit STR0013 reserve-account balance query

Submits a single-party STR0013 reserve-account balance query to BACEN and returns a correlation id plus a PENDING state. The answer (STR0013R1, carrying SldRB_CL — the conta Reservas Bancárias / Conta de Liquidação balance) arrives asynchronously and is read via GET /v1/str/reserve-balance-queries/. Lerian SPB projects the balance BACEN sends; it never computes a position.
