Show the Shopify orders behind a Freshdesk ticket

**Objective:** Give a support agent the Shopify order context for Freshdesk ticket `{ticket-id}`, looking at orders from the last `{lookback-days}` days (default 90).

**Step 1: Read the ticket (Freshdesk server)**

Call `freshdesk-get-tickets` with `ticket-id` set to `{ticket-id}`. If nothing comes back, say the ticket was not found and stop. Note `subject`, `status`, `priority`, `requester-email` and `created-at`.

**Step 2: Find the customer (Shopify server)**

Call `shopify-get-customer` with `email` set to the ticket's `requester-email`. If no customer matches, report that the requester has no Shopify customer record and stop after Step 4. If several match, list them and stop.

**Step 3: Pull their orders (Shopify server)**

Call `shopify-get-order` with `customer-id` from Step 2 and `created-at.from` set to the lookback date. For orders that are unfulfilled or partially fulfilled, call `shopify-get-fulfillment` with `order-id` to get `shipment-status` and `tracking-number`. Call `shopify-get-refund` with `customer-id` to list refunds in the same window.

**Step 4: Report**

Show the ticket summary, then a table of orders (order-number, created-at, total-price, financial-status, fulfillment-status, tracking), then any refunds. End with a short note on which order the ticket most likely concerns, judged from the ticket subject and dates, and say it is a guess.

**Rules & Guidelines:**

* `freshdesk-get-tickets` is on the Freshdesk server; `shopify-get-customer`, `shopify-get-order`, `shopify-get-fulfillment` and `shopify-get-refund` are on the Shopify server.
* Read-only. Never call `freshdesk-update-ticket`, `freshdesk-add-ticket-note`, `freshdesk-reply-to-ticket`, `shopify-update-order` or any other add, update or delete tool.

**Validation:**

* Match emails case-insensitively. The ticket's `requester-email` is the only join key; do not match on name.
* If either server returns nothing, say which one and report what the other returned.
