Embat Balances API

`Balance` represents the end-of-day balance of a bank product (account) for a given calendar day. Embat records one balance per product per day, expressed both in the product's own currency (`balance`) and, when available, in the company accounting currency (`accountingBalance`, converted using the exchange rate as of that day).Each balance is linked to a `Product` (a bank account, credit line, card...) held at one of the company's connected `Banks`. Balances whose linked product no longer exists in Embat are not returned.**Typical flow:** use `GET /balances/{companyId}` to read the daily balance history of a company's bank products, filtering by `productId` and by date range, or `GET /balances/{companyId}/{id}` to retrieve a single balance you already know the `id` of — for example after obtaining it from a previous list call.
