Check that Chargebee payments were applied in GP

**Objective:** Check whether Chargebee payments received in the last {lookback-days} days (default 30) have been applied in PowerGP, optionally for one {customer} only.

**Step 1: Chargebee payments**

Call `chargebee-get-transaction` (chargebee) with `status` set to success, `type` set to payment, `date.from` set to the lookback start, and `customer-id` if the customer was resolved with `chargebee-get-customer` (`company.contains`). Record `id`, `customer-id`, `amount`, `date`, `reference-number`.

**Step 2: Resolve each customer**

For each distinct `customer-id` call `chargebee-get-customer` with `id` to get `company`. Then call `powergp-online-get-customers` (powergp-online-ai) with `customer-name.contains` set to that company. If none match, list the payments as customer not found in PowerGP.

**Step 3: Look for the receipt**

Call `powergp-online-get-receivablesapply` with `customer-number` and `applied-date.from` set to the lookback start. A Chargebee payment counts as applied when an applied amount equals `amount` and the date is within 7 days, or `reference-number` appears in an applied document number.

**Step 4: Report**

Table with Chargebee transaction id, customer, amount, date, and status Applied or Not found in PowerGP. End with counts and the total of unapplied amounts.

**Rules & Guidelines:**

* Tools prefixed powergp-online- belong to the powergp-online-ai server; tools prefixed chargebee- belong to the chargebee server. Both servers must be connected.
* Read-only: call only the get tools named above. Never create, change or delete anything in either system.
* Never print card or bank details; report ids, names and amounts only.

**Validation:**

* If Chargebee has no payments in the window, say so and stop.
* Amounts in different currencies are listed as not comparable.
