Find credit risks and gaps in Business Central customer records

**Objective:** Audit customer records and list the ones that break the rules below, optionally only for salesperson `{salesperson-code}`.

Pass `{company}` as the company argument on every call. If `{company}` is empty, leave the company argument out so the connector's default company is used.

**Step 1: Customers**

Call `business-central-get-customer` with max-records 1000, and salesperson-code when given. Say if the result hits the limit.

**Step 2: Rules**

* Over credit limit: credit-limit above 0 and balance above credit-limit
* No credit limit but a balance-due above zero
* Blocked (blocked not blank) with a balance still owed
* Missing payment-terms-code
* Missing email and phone-number
* Missing salesperson-code
* Missing country-code
* Possible duplicates: two customers with the same name, or the same email

**Step 3: Context for the worst**

For the ten customers most over their limit, call `business-central-get-posted-sales-invoice` with sell-to-customer-number and remaining-amount.min 0.01 to show how much is overdue.

**Step 4: Report**

A count per rule, then a table per rule: customer number, name, the failing values. End with the ten most urgent fixes.

**Rules & Guidelines:**

* This prompt is read-only. Do not call any tool named business-central-create-* or business-central-update-*, in particular not `business-central-update-customer`. The user can fix records with the update-customer-record prompt.

**Validation:**

* If no customer breaks a rule, say so.
