Turn overdue Business Central invoices into Asana tasks

**Objective:** Find Business Central posted sales invoices overdue by at least `{min-days-overdue}` days (default 1) with a remaining amount of at least `{min-amount}` (default 0.01), and create one Asana collection task per invoice in project `{project-id}`, assigned to the customer's salesperson. Nothing is created until the user confirms.

**Step 1: Find the overdue invoices in Business Central**

Work out the cut-off date as today minus `{min-days-overdue}` days (1 if empty). Call `business-central-get-posted-sales-invoice` with `due-date.to` set to the cut-off, `remaining-amount.min` set to `{min-amount}` (0.01 if empty) and `company` set to `{company}` if given. Keep `invoice-number`, `sell-to-customer-number`, `sell-to-customer-name`, `due-date`, `remaining-amount`, `currency-code` and `salesperson-code`.

**Step 2: Resolve each salesperson to an Asana user**

For each distinct `salesperson-code`, call `business-central-get-salesperson` and take its `email`. Then call `asana-get-user` with `email` set to it and take the `user-id`. If the invoice has no salesperson, the salesperson has no email, or no Asana user has that email, leave the task unassigned and say why.

**Step 3: Skip invoices that already have a task**

For each invoice, call `asana-get-tasks` with `name.contains` set to the invoice number. If an open task already exists, skip the invoice and list it as already tracked.

**Step 4: Confirm**

Show the plan as a table: invoice number, customer, due date, days overdue, remaining amount, assignee (or unassigned and why), and the task name. Task name format: `Collect <invoice-number> - <customer name> - <remaining-amount> <currency-code>`. Due on: today plus 3 days. Ask the user to confirm, or to remove rows. Do not continue without a yes.

**Step 5: Create the tasks**

For each confirmed row, call `asana-create-task` once with `name` as above, `project-ids` set to `{project-id}`, `assignee-id` set to the user id if resolved, `due-on` as above, and `notes` giving the customer number, invoice number, original due date, remaining amount and that it was created from Business Central.

**Step 6: Report**

List each task created with its `permalink-url`, each invoice skipped as already tracked, and each failure with the error.

**Rules & Guidelines:**

* `business-central-get-posted-sales-invoice` and `business-central-get-salesperson` are on the business-central server; `asana-get-user`, `asana-get-tasks` and `asana-create-task` are on the asana server.
* `asana-create-task` is the only write tool this prompt may call, and only after Step 4's confirmation. Do not call `asana-update-task`, `asana-create-comment` or any other asana write tool.
* Do not call any business-central create or update tool. This prompt never changes Business Central.

**Validation:**

* If no invoices are overdue, say so and stop.
* If more than 25 invoices qualify, show the 25 with the largest remaining amount and ask whether to include the rest.
* If `asana-create-task` fails for one invoice, report it and continue with the rest.
