`POST /accounting/vendor-bills/search`

Read-only: A read that takes its filters in the body. Changes nothing, and ignores Idempotency-Key.

Searches vendor bills. Each match has the same fields GET accounting/vendor-bills/:id returns, with its line items and their amortization schedules, but without the bill's approval decisions.

The purchase-order filters match at line level. A bill matches when any of its lines is linked to a line of that purchase order.
