Start each day with a ranked collections list

**Objective:** Produce a collections list of invoices past their due date that still have an amount due, for customer `{customer}` (all if blank) and invoice totals of at least `{min-total}` (no minimum if blank).

**Step 1: Pull overdue invoices**

Call `dynamics-365-sales-get-invoices` with `due-date.to` = yesterday, `customer` if given, and `total-amount.min` = `{min-total}` if given. Set `max-records` to 500. Keep only invoices whose `amount-due` is above 0 and whose `status-reason` is not a paid or cancelled value.

**Step 2: Age them**

Bucket each invoice by days past `due-date`: 1 to 30, 31 to 60, 61 to 90, over 90.

**Step 3: Context for the top customers**

For the 5 customers with the most overdue, call:

* `dynamics-365-sales-get-accounts` with `account-name` = the customer to get the credit limit, main phone, email and owner
* `dynamics-365-sales-get-incidents` with `customer` = the customer and open status, since an open complaint often explains non-payment
* `dynamics-365-sales-get-activitypointers` with `regarding` = the customer, to see when they were last contacted

**Step 4: Report**

1. Total overdue and the total per ageing bucket.
2. By customer, largest first: overdue total, oldest invoice age, count of invoices, credit limit, and whether overdue exceeds the credit limit.
3. The invoice lines: invoice ID, name, customer, due date, days overdue, total, amount due, payment terms.
4. For the top 5 customers: who to contact, the last contact date, and any open case that may be holding up payment.

**Rules & Guidelines:**

* This prompt is read-only. Do NOT call any create or update tool: `dynamics-365-sales-create-account`, `dynamics-365-sales-create-contact`, `dynamics-365-sales-create-lead`, `dynamics-365-sales-create-opportunity`, `dynamics-365-sales-create-case`, `dynamics-365-sales-create-task`, `dynamics-365-sales-create-note`, `dynamics-365-sales-create-phone-call`, `dynamics-365-sales-update-account`, `dynamics-365-sales-update-contact`, `dynamics-365-sales-update-lead`, `dynamics-365-sales-update-opportunity`, `dynamics-365-sales-update-case`.
* Amounts are in each invoice's own currency; do not add totals across currencies. If invoices use more than one currency, report totals per currency.

**Validation:**

* If nothing is overdue, say so and state the filters used.
* If `{min-total}` is not a number, ignore it and say so.
