Find BigCommerce refunds that have no HubSpot ticket

**Objective:** List BigCommerce orders created in the last `{lookback-days}` days (default 30) with a refund of at least `{min-refund}` (default 1), and show whether the customer has any HubSpot ticket.

**Step 1: Find refunded orders in BigCommerce**

Call `bigcommerce-get-order` with `date-created.from` set to today minus the lookback, `refunded-amount.min` set to `{min-refund}`, and `max-records` of 50. Keep `id`, `billing-email`, `billing-last-name`, `total-including-tax`, `refunded-amount`, `date-created`.

**Step 2: Check HubSpot for tickets**

For each order call `hubspot-get-contacts` with `email` set to the `billing-email`. If found, call `hubspot-get-tickets` with `contact-id` set to the contact `record-id` and `create-date.from` set to the order `date-created`. If no contact exists, mark the order as having no HubSpot contact.

**Step 3: Report**

A table: order id, customer email, total, refunded, ticket status (none, open, closed, or no contact). Put orders with no ticket first. End with counts for each ticket status.

**Rules & Guidelines:**

* `bigcommerce-get-order` is on the bigcommerce server; `hubspot-get-contacts` and `hubspot-get-tickets` are on the hubspot server.
* Read only. Do not call `hubspot-add-ticket`, `hubspot-update-ticket`, `hubspot-add-contact-note` or any write tool on bigcommerce.

**Validation:**

* If no refunded orders are found, say so and stop.
* Orders with no `billing-email` are listed as unmatchable.
