Hold deals with customers who are not paying

**Objective:** List customers in Business Central company `{company}` (default: the connector's default company when blank) with at least `{min-overdue-amount}` (default 1000) overdue, and show the open pipeline each one has in Dynamics 365 Sales, so sales can hold or escalate those deals.

**Step 1: Read overdue invoices in Business Central**

Call `business-central-get-posted-sales-invoice` with remaining-amount.min set to 0.01, due-date.to set to yesterday's date and max-records 500. Group the rows by sell-to-customer-number and sum remaining-amount; keep the oldest due-date and the sell-to-customer-name. Keep only customers whose overdue total is at least `{min-overdue-amount}` (default 1000). If none qualify, report that and stop.

**Step 2: Add customer context in Business Central**

For each qualifying customer, call `business-central-get-customer` with customer-number set to the sell-to-customer-number. Keep credit-limit, balance-due, blocked and salesperson-code.

**Step 3: Find the account and its open deals in Dynamics 365 Sales**

For each customer, call `dynamics-365-sales-get-accounts` with account-number set to the Business Central customer-number; if nothing comes back, call it again with account-name.contains set to the customer name. If still nothing, mark the customer as not in Dynamics 365 Sales and continue with the next one.

For each matched account, call `dynamics-365-sales-get-opportunities` with potential-customer set to the account-name and status set to Open, and `dynamics-365-sales-get-salesorders` with customer set to the account-name. Keep open opportunities (topic, est-revenue, est-close-date, owner) and orders that are not yet fulfilled (name, total-amount, status-reason).

**Step 4: Report**

A table sorted by overdue total, highest first: customer number, customer name, overdue total, oldest due date, days overdue, blocked, open opportunity count and est-revenue total, unfulfilled order total, and the Dynamics 365 Sales owner. Under the table, list each at-risk opportunity with its owner so they can be contacted.

**Rules & Guidelines:**

* Tools named dynamics-365-sales-* are on the dynamics-365-sales server; tools named business-central-* are on the business-central server.
* This prompt is read-only. Do NOT call `dynamics-365-sales-update-opportunity`, `dynamics-365-sales-create-task`, `business-central-update-customer` or any other create or update tool.

**Validation:**

* If 500 invoices come back, say the list may be incomplete.
* If an account match is by name only, mark it so the user can check it.
* Do not convert currencies; show each invoice total in its own currency-code and say when they are mixed.
