Find paying 2Checkout customers missing from Freshdesk

**Objective:** Find 2Checkout customers in country `{country-code}` (optional) whose email has no matching Freshdesk contact, up to `{max-customers}` customers (default 50).

**Step 1: Read 2Checkout customers**

Call `2checkout-get-customer` with `max-records` set to `{max-customers}`. If `{company}` is given, pass it as `company`. Keep `customer-reference`, `first-name`, `last-name`, `company`, `email` and `country-code`. If `{country-code}` is given, discard customers with a different `country-code`.

**Step 2: Look each email up in Freshdesk**

For each customer with an email, call `freshdesk-get-contacts` with `email` set to that value and `max-records` 1. A customer with no result is missing from Freshdesk.

**Step 3: Report**

Counts of customers checked, matched and missing. Then a table of the missing customers (name, company, email, `customer-reference`). Where a match exists but the Freshdesk `name` clearly differs from the 2Checkout name, list it under Name mismatches.

**Rules & Guidelines:**

* `freshdesk-*` tools belong to the Freshdesk server; `2checkout-*` tools belong to the 2Checkout server. Both servers must be connected.
* The shared key across the two systems is the customer email address. Compare emails case-insensitively and trim spaces.
* Read-only. Do not call `freshdesk-add-contact` or `freshdesk-update-contact`; only report the gaps.

**Validation:**

* If the customer list is empty, say so and stop.
* If emails are blank, list those customers as unmatchable.
