Get missing WooCommerce sales into Rillet without duplicate invoices

**Objective:** Record every WooCommerce order created from `{from-date}` to `{to-date}` (default: yesterday) that has no Rillet invoice yet as a Rillet AR-only invoice against the Rillet product `{rillet-product-name}`, after the user confirms the list.

**Step 1: Read the WooCommerce orders**

Call `woocommerce-get-order` with created-date.from and created-date.to set to the range and no status filter. Keep only orders whose status is processing, completed, on-hold or refunded. Skip pending, failed and cancelled orders. Note order-id, order-number, created-date, status, customer-email, billing-first-name, billing-last-name, currency and total.

Call `woocommerce-get-order-line` with date-created.from and date-created.to set to the same range, and sum line-total-tax by order-id. That is each order's item tax. WooCommerce does not report shipping tax on the order lines, so any shipping tax stays inside the net amount.

**Step 2: Find the gaps**

Call `rillet-get-invoices` (it takes no filters). An order already has an invoice if any invoice-number equals the order-number, compared with and without a leading #, or equals the order-id. Keep only the orders with no match.

**Step 3: Resolve the Rillet references**

* Product: call `rillet-get-products` and find the product whose name equals `{rillet-product-name}`. If none or more than one matches, list the candidates and stop.
* Customer: call `rillet-get-customer-emails` and match the order customer-email to email, ignoring case. If exactly one Rillet customer-id matches, use it. Otherwise, if `{fallback-customer-name}` was given, call `rillet-get-customers` and use the customer whose name equals it. If neither resolves, list the order under "no customer" and do not create it.

**Step 4: Confirm**

Show a table of the invoices you will create: order-number, date, status, Rillet customer name, net amount (total minus item tax), tax, total, currency. Show the "no customer" orders separately. Ask the user to confirm. Create nothing until they do.

**Step 5: Create**

For each confirmed order, call `rillet-add-invoice-ar-only` once with:

* invoice-number: the WooCommerce order-number, exactly as WooCommerce shows it
* invoice-date: the order created-date
* customer-id: the resolved Rillet customer
* external-system: WooCommerce
* external-id: the WooCommerce order-id
* line1-product-id: the resolved product, line1-quantity 1, line1-currency the order currency
* line1-total: total minus item tax
* tax-amount: the item tax, tax-currency the order currency (leave both out when the item tax is 0)
* line1-description: WooCommerce order followed by the order-number

**Step 6: Report**

A table of created invoices with the returned id, a list of any that failed with the error as returned, and the orders skipped for no customer.

**Rules & Guidelines:**

* `woocommerce-get-order` and `woocommerce-get-order-line` are on the woocommerce server. `rillet-get-invoices`, `rillet-get-products`, `rillet-get-customer-emails`, `rillet-get-customers` and `rillet-add-invoice-ar-only` are on the rillet server.
* `rillet-add-invoice-ar-only` is the only write tool this prompt may call, once per confirmed order. Do not call `rillet-add-invoice`, `rillet-add-invoice-revenue-only`, `rillet-update-invoice` or `rillet-add-invoice-payment`. Recording the payment is the apply-woocommerce-payments prompt.
* WooCommerce is read-only here. Do not call `woocommerce-update-order`, `woocommerce-add-order-note` or any other woocommerce write tool.
* Re-read `rillet-get-invoices` immediately before creating if more than a few minutes passed since Step 2, so a second run does not create duplicates.

**Validation:**

* If there are no gaps, say every order in the range already has a Rillet invoice and stop.
* If a create fails, report it and continue with the rest. Do not retry with altered values.
* If the user does not confirm, create nothing.
