Check Chargebee payments were applied in Dynamics GP

**Objective:** For the customer `{customer-id}` check that payments recorded in Chargebee since `{date-from}` (default: the last 60 days) were applied in Dynamics GP. Use `{gp-company}` as the GP company when given.

**Step 1: Chargebee payments**

Call `chargebee-get-transaction` (chargebee server) with `customer-id`, `date.from`, and `status` for successful payments if that filter accepts it. Keep id, date, amount, amount-unused, reference-number, payment-method and gateway. Skip failed transactions but count them.

**Step 2: GP applications**

Call `dynamics-gp-get-rm-trx-apply` (dynamics-gp server) with `customer-id` and `document-date.from`. Also call `dynamics-gp-get-rm-trx` (dynamics-gp server) with the same customer and date to see unapplied cash receipts.

**Step 3: Match**

Match each Chargebee payment to a GP cash receipt by amount-applied or document-amount equal to the payment amount within 5 days, and by reference-number appearing in `document-number`.

**Step 4: Report**

List payments applied in both systems, payments in Chargebee with no GP receipt, payments in GP with no Chargebee transaction, and payments received but still unapplied (Chargebee `amount-unused` above zero, or a GP receipt with a current-transaction-amount above zero).

**Rules & Guidelines:**

* `chargebee-get-transaction` is on the chargebee server; `dynamics-gp-get-rm-trx-apply` and `dynamics-gp-get-rm-trx` are on the dynamics-gp server.
* Read only. Do not call any write tool on either server.

**Validation:**

* If nothing is returned on one side, report the other side and say so.
* If the currencies differ, list the payments without comparing amounts.
