Reconcile 2Checkout orders with Business Central invoices

**Objective:** For 2Checkout order `{order-reference}`, find the Business Central sales document that billed it and compare the amounts. If `{order-reference}` is empty, check every order from `{order-date-from}` to `{order-date-to}` (dates as YYYY-MM-DD, default the last 7 days).

**Step 1: Read the order in 2Checkout**

If an order reference was given, call `2checkout-get-order` with `external-reference` set to `{order-reference}`; if nothing comes back, call `2checkout-get-orderitem` and match on `reference-number`. If no reference was given, call `2checkout-get-orderitem` with `order-date.from` and `order-date.to` and group the lines by `reference-number`. Note `reference-number`, `status`, `currency`, `gross-discounted-price` and `order-date` for each order. Skip orders with `test-order` true.

**Step 2: Find the invoice in Business Central**

For each order call `business-central-get-posted-sales-invoice` with `external-document-number` set to the 2Checkout `reference-number`. If nothing is returned, call `business-central-get-sales-transaction` with the same `external-document-number` to find an unposted invoice or order.

**Step 3: Compare**

Compare 2Checkout `gross-discounted-price` with Business Central `total-amount-including-tax`, and `currency` with `currency-code`. Classify each order as Matched, Amount differs, Currency differs, Billed but not posted (only found by `business-central-get-sales-transaction`), or Missing from Business Central.

**Step 4: Report**

Give a table with one row per order: reference, order date, 2Checkout amount, Business Central document number, Business Central amount and classification. Finish with counts per classification.

**Rules & Guidelines:**

* Tools named the 2checkout prefix are on the 2checkout server and tools named the business-central prefix are on the business-central server. Both servers must be connected.
* This is a read-only job. Never call any 2checkout or business-central create, update, add, order or subscription action tool.
* Business Central tools take an optional company parameter; only use it if the user named a company.

**Validation:**

* If 2Checkout returns no orders, say so and stop.
* Differences under 0.01 are rounding and count as Matched.
* A Business Central amount that differs because of tax may be legitimate; show both figures and flag it for review instead of calling it an error.
