Audit a vendor's payables and 1099 setup in one answer

**Objective:** Build a full picture of vendor `{vendor}` in `{company}` (default company if empty): balance, open documents, payment history and 1099 setup for year `{year}` (default current calendar year).

**Step 1: Find the vendor**

Call `powergp-online-get-vendors` with `vendor-id` equal to `{vendor}`. If nothing matches, call it again with `vendor-name.contains` set to `{vendor}`. If more than one vendor matches, list them (id, name, balance) and stop.

**Step 2: Open and recent documents**

Call `powergp-online-get-payablestransactions` with the vendor id. Separate open documents (unapplied amount above zero) from closed ones, and note any past `due-date`.

**Step 3: Payments applied**

Call `powergp-online-get-payablesapply` with the vendor id to see which payments were applied to which documents.

**Step 4: 1099**

Call `powergp-online-get-payables1099transactions` with the vendor id and `document-date.from` and `document-date.to` set to the year. Report whether `tax-id-number` is present, the 1099 type, and the total document amount.

**Step 5: Report**

Give: vendor header (id, name, class, balance, last invoice, last payment), open documents table, payments summary, 1099 total and any gaps (missing tax id, 1099 type blank on a document).

**Rules & Guidelines:**

* This prompt is read-only. Only the get tools on this server exist; never try to change, post, approve, release or delete anything in Dynamics GP.
* Do not call customer or receivables tools.
* Only report a missing tax id when the 1099 call returned rows with it blank; do not guess otherwise.

**Validation:**

* If the vendor has no 1099 rows, say so rather than implying a problem.
