Find enabled Akeneo products that Business Central has blocked

**Objective:** Find Akeneo products for brand `{brand}` (default: all brands) that are enabled for sale but whose Business Central item is blocked, or has inventory at or below `{inventory-threshold}` (default 0).

**Step 1: Read the enabled products from Akeneo**

Call `akeneo-get-product` (Akeneo server) with `enabled` true, `brand` set to `{brand}` if given, and `max-records` 100. Keep `identifier`, `product-name`, `brand` and `uuid`. If none, say so and stop.

**Step 2: Read the matching items from Business Central**

For each product call `business-central-get-item` (Business Central server) with `item-number` set to the `identifier`. Keep `blocked`, `inventory`, `quantity-on-purchase-order` and `vendor-name`. A product with no item is reported separately as not in Business Central.

**Step 3: Report**

Two tables: blocked items (identifier, name, brand) and items at or below the threshold (identifier, name, inventory, on purchase order, vendor). Then a short list of products with no item. Order by brand.

**Rules & Guidelines:**

* `akeneo-get-product` is Akeneo; `business-central-get-item` is Business Central.
* Read-only. Do not call `akeneo-update-product`, `business-central-update-item` or any other write tool. Recommend follow-up in words only.

**Validation:**

* If the Akeneo list is capped at 100, say the result may be incomplete.
* If an item lookup returns several rows, list them all and flag the product.
