Reconcile Ramp purchase orders to Business Central

**Objective:** For Ramp purchase orders created from `{created-from}` (optionally with name containing `{po-name}`), find the matching Business Central purchase order and compare amounts and billing progress. Read-only.

**Step 1: Read the Ramp orders**

Call `ramp-get-purchase-order` (Ramp server) with `created-at.from` set to `{created-from}`, `name.contains` set to `{po-name}` when given, and `max-records` 100. Keep `id`, `purchase-order-number`, `name`, `amount`, `currency-code`, `spend-total-amount`, `billing-status`, `receipt-status`.

**Step 2: Find each order in Business Central**

For each order call `business-central-get-purchase-transaction` (Business Central server) with `document-type` Order and `document-number` set to the Ramp `purchase-order-number`. If nothing returns, mark the order as not found in Business Central (the tool cannot filter by the vendor's own order number). Keep `document-number`, `buy-from-vendor-name`, `total-amount-including-tax`, `total-outstanding-amount`, `status`, `order-date`.

**Step 3: Report**

Table per outcome: matched and equal; matched with a different total; Ramp orders not found in Business Central; matched where Ramp `spend-total-amount` exceeds the Business Central invoiced amount (total minus outstanding). Show `billing-status` and `receipt-status` beside each. Finish with counts.

**Rules & Guidelines:**

* `ramp-get-purchase-order` is on the Ramp server; `business-central-get-purchase-transaction` is on the Business Central server.
* Read-only. Do not call `ramp-purchase-order-update`, `ramp-purchase-order-archive`, `business-central-create-purchase-order` or `business-central-update-purchase-order`.

**Validation:**

* If Ramp returns none, report that and stop.
* If a Ramp order has no purchase order number, list it as unmatchable.
* Compare amounts only when currencies agree; otherwise show both values.
