Open a deposit (acompte)
Opens a deposit (acompte) against a special order with an upfront down-payment, creating it open. The CALLER supplies the deposit id — it must be unique, so choose a stable, collision-free identifier (a duplicate is rejected, never silently merged). Money is integer cents; the down-payment must not exceed the order total. 409s when a deposit with the same id already exists; 422s when the down-payment overpays the order total.
Authorizations
Authorization: Bearer <token>. Accepts EITHER a Keycloak access token (scopes-in-token) OR an opaque POS session token; both resolve to the same pos.* scope vocabulary the route guards enforce.
