Set Business Central invoices beside Mailchimp campaign revenue

**Objective:** For the Mailchimp campaign `{campaign-title}`, compare the e-commerce revenue Mailchimp attributes to it with the sales Business Central invoiced to the same customers in the `{days-after-send}` days after it was sent (default 30). Use the Business Central company `{company}`; if it is empty, omit the `company` filter.

**Step 1: Find the campaign**

Call `mailchimp-get-report` with `campaign-title.contains` set to `{campaign-title}`. If more than one campaign matches, list them (campaign-title, send-date, emails-sent) and stop so the user can pick one. Note send-date, emails-sent, open-rate, click-rate and total-revenue.

**Step 2: Orders Mailchimp attributes to it**

Call `mailchimp-get-order` with `outreach-name.contains` set to the campaign title. Collect the distinct customer-email-address values with each one's summed order-total and currency-code.

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

For each email, call `business-central-get-customer` with `email` set to it to get the customer-number. Then call `business-central-get-posted-sales-invoice` with `sell-to-customer-number` set to it, `posting-date.from` set to the send-date and `posting-date.to` set to the send-date plus the window. Sum total-amount per customer.

**Step 4: Report**

The campaign's headline numbers, then a table: email, customer-number, Mailchimp attributed order total, Business Central invoiced total in the window, invoice count. Finish with the two totals side by side and the number of buyers not found in Business Central.

**Rules & Guidelines:**

* `mailchimp-get-report` and `mailchimp-get-order` are on the mailchimp server. `business-central-get-customer` and `business-central-get-posted-sales-invoice` are on the business-central server.
* Business Central invoices in the window are correlation, not proof of attribution. Say so once in the report.
* This prompt is read-only. Do NOT call `mailchimp-replicate-campaign` or any business-central create or update tool.

**Validation:**

* If Mailchimp attributes no orders to the campaign, report the campaign metrics and stop.
* If a buyer's email is not a Business Central customer, list them as not found and continue.
* If currency-code differs between the two systems for a buyer, show both amounts with their currency and do not add them together.
