Reconcile WooCommerce sales tax with Rillet before you file

**Objective:** Compare the sales tax WooCommerce collected on orders from `{from-date}` to `{to-date}` (default: the previous calendar month), net of refunded tax, with the net credits posted to Rillet account `{tax-account-code}` in the same period.

**Step 1: Tax collected in WooCommerce**

Call `woocommerce-get-order-line` with date-created.from and date-created.to set to the period. Keep lines whose order-status is processing, completed, on-hold or refunded. Sum line-total-tax by currency, and count the orders.

WooCommerce order lines carry item tax only. Shipping tax is not in this figure: say so in the report.

**Step 2: Tax refunded in WooCommerce**

Call `woocommerce-get-refund-line` with created-date.from and created-date.to set to the period. Sum line-item-total-tax by currency, as a positive number whatever its sign.

**Step 3: Tax posted in Rillet**

Call `rillet-get-accounts` filtered by account-code `{tax-account-code}` and confirm it exists. Then call `rillet-get-journal-entry-lines` (no filters) and keep lines whose account-code is `{tax-account-code}` and whose date falls in the period. Net them as credits minus debits, by currency.

**Step 4: Report**

A table by currency:

| | Amount |
|---|---|
| WooCommerce item tax collected | |
| WooCommerce item tax refunded | |
| WooCommerce net item tax | |
| Rillet net credits to the tax account | |
| Difference | |

If there is a difference, look for its likely causes and list them: shipping tax (not in the WooCommerce figure), refunds booked in a different period, orders not yet invoiced in Rillet (check `rillet-get-invoices` for invoice-numbers equal to the order-numbers), or tax filings and payments posted to the same account.

**Rules & Guidelines:**

* `woocommerce-get-order-line` and `woocommerce-get-refund-line` are on the woocommerce server. `rillet-get-accounts`, `rillet-get-journal-entry-lines` and `rillet-get-invoices` are on the rillet server.
* This prompt is read-only. Do not call `rillet-add-journal-entry`, `rillet-update-journal-entry` or any other write tool. If an adjustment looks necessary, say what it would be and leave posting it to the user.

**Validation:**

* If `{tax-account-code}` is not a Rillet account, stop and say so.
* If there are no WooCommerce orders in the period, report WooCommerce tax as zero and still show the Rillet side.
* Show every currency separately. Do not convert.
