Check a BigCommerce order against its Dynamics 365 Sales order

**Objective:** Check whether BigCommerce order `{order-id}` has a matching sales order or invoice in Dynamics 365 and whether the amounts agree.

**Step 1: Read the BigCommerce order**

Call `bigcommerce-get-order` (BigCommerce server) with `id` set to `{order-id}`. Then call `bigcommerce-get-order-product` with `order-id` set to `{order-id}`. Record the billing name, billing email, company, order total including tax and the line items.

**Step 2: Find the customer in Dynamics 365**

Call `dynamics-365-sales-get-contacts` (Dynamics 365 server) with `email` set to the billing email, and use the contact's parent customer name. If none, call `dynamics-365-sales-get-accounts` with `account-name` set to the billing company.

**Step 3: Find the matching documents**

Call `dynamics-365-sales-get-salesorders` and `dynamics-365-sales-get-invoices` with `customer` set to the customer name from Step 2, and `total-amount.min` and `total-amount.max` set to the BigCommerce total plus or minus `{amount-tolerance}` (default 1.00). If nothing matches in range, repeat without the amount filter and list the nearest candidates.

**Step 4: Report**

Show the BigCommerce order total and lines next to the best Dynamics 365 match: amount, status, and difference. Verdict: Matched, Amount differs, or No match. For a match, compare line items using `dynamics-365-sales-get-salesorderdetails` with `order` set to the order name.

**Rules & Guidelines:**

* `bigcommerce-get-order` and `bigcommerce-get-order-product` are on the BigCommerce server; the Dynamics 365 Sales tools (names beginning dynamics-365-sales-) are on the Dynamics 365 Sales server.
* Read only. Never call any add, update, create or delete tool.

**Validation:**

* If the order id is not found in BigCommerce, stop.
* If currencies differ, show both currencies and do not compare the amounts.
