Stop sending promotions to customers collections is chasing

**Objective:** Find Business Central customers with a balance due of at least `{min-balance-due}` (default 1000) who are still active subscribers in Drip campaigns, so collections and marketing can agree what they receive. Use Business Central company `{bc-company}` if given.

**Step 1: Find customers with a balance due**

Call `business-central-get-customer` with `balance-due.min` set to `{min-balance-due}` (1000 if blank). Keep `customer-number`, `name`, `email`, `balance-due`, `blocked` and `salesperson-code`. Set aside customers with no email; you cannot match them.

**Step 2: Check each one in Drip**

For each customer with an email, call `drip-get-subscriber` with `email` set to that email, then `drip-get-campaign-subscriber` with the same `email`. A customer counts as still marketed to when the Drip `status` is active and at least one campaign subscription has an active `campaign-status`.

**Step 3: Report**

A table sorted by `balance-due` descending: customer number, name, email, balance due, blocked, salesperson, Drip status, lead score, active campaigns by name. Below it, give counts for: still marketed to, in Drip but unsubscribed, not in Drip, and no email in Business Central.

**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-remove-subscriber-from-campaign`, `drip-remove-subscriber-from-all-campaigns`, `drip-pause-campaign`, `drip-add-subscriber-tag` or `business-central-update-customer`. If the user wants to act, point them to the `sync-overdue-tag-to-drip` prompt.

**Validation:**

* If no customer meets the threshold, say so and stop.
* If Step 1 returns more than 100 customers, work through the 100 with the largest balance due and say how many were left out.
* Compare emails case-insensitively and ignoring surrounding spaces.
