Find Stripe customers that have no GP account

**Objective:** Find Stripe customers whose name has no match in Dynamics GP, checking up to `{max-customers}` Stripe customers (default 25), optionally only those created since `{created-from}`.

**Step 1: Read Stripe customers**

Call `stripe-get-customer` with `max-records` set to the limit and `created.from` if given. Keep `customer-id`, `name`, `email` and `created`.

**Step 2: Look each one up in GP**

For each Stripe customer with a name, call `powergp-online-get-customers` with `customer-name.contains` set to that name (try the first word if the full name returns nothing). Record the matching `customer-number` values. Treat a customer with no name as unmatched and say so.

**Step 3: Report**

Three lists: matched one-to-one, matched to several GP customers (show candidates), and unmatched. For each unmatched customer show `customer-id`, `name`, `email` and `delinquent`.

**Rules & Guidelines:**

* Tools prefixed powergp-online- belong to the powergp-online-ai server (Dynamics GP). Tools prefixed stripe- belong to the stripe server. Both servers must be connected.
* Read-only. Call only get tools. Never create, change or delete anything on either side.
* Pass `company` on every GP call when the user names one; otherwise state which company the GP data came from.
* Stripe amounts and GP amounts may use different currencies; compare only like currencies and flag the rest.

**Validation:**

* Name matching is approximate. Label a match as likely, not certain, and never claim two records are the same customer on name alone when an email or address contradicts it.
* If Stripe returns no customers, stop and say so.
