Compare BigCommerce sales with Rillet invoiced revenue

**Objective:** Compare what the store sold with what the ledger invoiced between `{from-date}` and `{to-date}` (YYYY-MM-DD), optionally for one `{currency}` (default: all).

**Step 1: Store sales (bigcommerce server)**

Call `bigcommerce-get-order` with `date-created.from` = `{from-date}`, `date-created.to` = `{to-date}` and `max-records` 250. If `{currency}` is given pass it as `currency-code`. Sum `total-including-tax`, `total-tax` and `refunded-amount` per `currency-code`, and count the orders. Note the number of orders in each `payment-status`.

**Step 2: Ledger invoices (rillet server)**

Call `rillet-get-invoices` and keep rows whose `invoice-date` falls in the same range. Sum `total`, `tax-amount` and `amount-due` per `currency`, and count them. Call `rillet-get-credit-memos` with `credit-memo-date.from` and `credit-memo-date.to` set to the range and sum `total` per `currency`.

**Step 3: Report**

Per currency: store orders (count, total), refunds, store net; ledger invoices (count, total), credit memos, ledger net; the difference and the percentage gap. Add the five largest store orders by `total-including-tax` and ask the reader to check whether each has an invoice (do not check them all).

**Rules & Guidelines:**

* `bigcommerce-*` tools are on the bigcommerce server; `rillet-*` tools are on the rillet server. Both servers must be connected.
* This prompt is read-only. Never call any bigcommerce `-add`, `-update` or `-delete` tool or any rillet `-add`, `-update`, `-apply`, `-unapply`, `-record`, `-set` or `-setup` tool.
* Quote ids and amounts exactly as returned. Do not guess a match.

**Validation:**

* Do not add amounts in different currencies together.
* If more than 250 orders exist in the range, say the store figure is a partial sum and narrow the dates.
* Timing differences (orders not yet invoiced) are expected; report them as a possible reason, not as an error.
