Find the Rillet invoice for a BigCommerce order and check it

**Objective:** For BigCommerce order `{order-id}`, find the matching Rillet invoice and report whether the totals and dates agree, using a tolerance of `{tolerance}` (default 0.01).

**Step 1: Read the order (bigcommerce server)**

Call `bigcommerce-get-order` with `id` = `{order-id}`. Keep `customer-id`, `billing-email`, `billing-last-name`, `total-including-tax`, `total-tax`, `currency-code`, `date-created`, `refunded-amount` and `payment-status`. If no order is found, stop. Call `bigcommerce-get-order-product` with `order-id` = `{order-id}` to list the line items (`sku`, `name`, `quantity`, `total-including-tax`).

**Step 2: Find the Rillet customer (rillet server)**

Call `rillet-get-customer-emails` and find the row whose `email` equals `billing-email` (case-insensitive). Take its `customer-id`. If there is no match, fall back to `rillet-get-customers` matching `name` on the billing name. If neither matches, report the order as having no Rillet customer and stop.

**Step 3: Find the invoice (rillet server)**

Call `rillet-get-invoices` and keep rows whose `customer-id` equals the one found. Prefer the row whose `purchase-order-number`, `memo` or `invoice-number` contains `{order-id}`. Otherwise choose the invoice whose `total` is closest to the order total and whose `invoice-date` is within 7 days of `date-created`, and say the match was inferred.

**Step 4: Report**

A side-by-side table: order total, invoice `total`, difference, currency on each side, order date, `invoice-date`, invoice `status`, `amount-due`. State clearly whether they agree within the tolerance. If the order has a `refunded-amount`, list Rillet credit memos from `rillet-get-credit-memos` for that `customer-id` beside it.

**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:**

* If the currencies differ, report both and do not convert.
* If several invoices fit equally well, list them and do not pick one.
* If there is no invoice for the customer, report the order as not yet invoiced.
