Set default limit for accountingTransfers backend API

[mkurapov]

Context

Currently, in our accountingTransfers query in the backend API, because we do not yet have pagination, we only allow providing a limit value to how many transfers are returned. For this query, when using Tigerbeetle, we have a limit set to 100_000. This is also what is mentioned in the description.

We should set a smaller default limit for both accounting services, (20?) and make sure to update the description in the GraphQL API to be accounting service agnostic.

Todos

• Update limit in both of the accounting services to be 20 for fetching transfers
• Update GraphQL API description
• Tag writer @brad-dow to take a look at the description change
