Answer what a Drip campaign audience was invoiced

**Objective:** Show how much the subscribers of Drip campaign `{campaign-name}` have been invoiced in Business Central since the campaign was created. Use Business Central company `{bc-company}` if given.

**Step 1: Find the campaign**

Call `drip-get-campaign` with `name.contains` set to `{campaign-name}`. If more than one campaign matches, list them (name, `campaign-id`, `status`, `created-date`) and stop so the user can pick. If none match, say so and stop. Note its `created-date`; that is the start of the window.

**Step 2: List its subscribers**

Call `drip-get-campaign-subscriber` with `campaign-id` set to the campaign's `campaign-id` (`max-records` 200). Keep each `email` and `campaign-status`.

**Step 3: Carry each email into Business Central**

For each email, call `business-central-get-customer` with `email` set to it. For each matched customer, call `business-central-get-posted-sales-invoice` with `sell-to-customer-number` set to its `customer-number` and `posting-date.from` set to the campaign's created date. Sum `total-amount` (before tax).

**Step 4: Report**

* Campaign name, status, created date, subscribers read
* Matched to a customer: count and percent; invoiced since start: total and number of invoices
* Top 10 customers by invoiced amount: name, customer number, email, invoiced
* Subscribers with no matching customer: count only, plus up to 10 example emails

State plainly that this is invoiced revenue from people on the campaign, not proof the campaign caused it.

**Rules & Guidelines:**

* Tools whose names start with drip are on the drip server; tools whose names start with business-central are on the business-central server. Pass `{bc-company}` only to business-central tools.
* This prompt is read-only. Do NOT call `drip-pause-campaign`, `drip-activate-campaign`, `drip-remove-subscriber-from-campaign` or any Business Central create or update tool.

**Validation:**

* If the campaign has 200 subscribers or more, say the result covers the first 200 only.
* If two customers share an email, count the invoices of both and flag the duplicate.
* Compare emails case-insensitively and ignoring surrounding spaces.
