Post Stripe invoices to Dynamics GP without duplicates

**Objective:** Find the finalized Stripe invoices created from `{start-date}` to `{end-date}` that have no receivables document in Dynamics GP, and add the ones the user confirms to GP batch `{batch-number}` in company `{company}` (empty means the default company).

**Step 1: Read the Stripe invoices**

Call `stripe-get-invoice` with `created-date.from` = `{start-date}` and `created-date.to` = the day after `{end-date}`. Keep invoices with status `open`, `paid` or `uncollectible`, and drop any created after `{end-date}`.

**Step 2: Skip the ones GP already has**

For each invoice, call `dynamics-gp-get-rm-trx` with `document-number` = the Stripe `number`. If a record comes back, skip the invoice.

**Step 3: Map the customer**

For each remaining invoice, call `dynamics-gp-get-rm-customer` with `customer-name.contains` = the Stripe `customer-name`, and accept the GP customer whose `main-email-address` equals the Stripe `customer-email`, ignoring case. If none matches, or more than one does, mark the invoice as unmapped. Do not post it.

**Step 4: Propose and confirm**

Show a table: Stripe number, created date, due date, customer, GP customer ID, total, status. Show the unmapped invoices separately and suggest `backfill-stripe-customers`. Then stop and wait. Post nothing until the user confirms, and post only the rows they confirm.

**Step 5: Post**

For each confirmed invoice, call `dynamics-gp-rm-trx-add` once with `document-type` = the code the tool lists for an invoice, `document-number` = the Stripe `number`, `customer-id` = the GP customer ID, `document-date` = the Stripe created date, `due-date` = the Stripe due date, `document-amount` and `sales-amount` = the Stripe `total`, `batch-number` = `{batch-number}`, `description` = "Stripe " followed by the Stripe number, `create-distributions` = 1 and `company` = `{company}`. Stripe totals include tax, so do not also set `tax-amount`.

**Step 6: Report**

A table of what was posted, what failed (with the error) and what was skipped, and a closing line saying the batch still has to be posted in Dynamics GP.

**Rules & Guidelines:**

* `stripe-get-invoice` is on the stripe server. The dynamics-gp tools are on the dynamics-gp server.
* The only write tool this prompt may call is `dynamics-gp-rm-trx-add`, once per confirmed invoice. Do not call `dynamics-gp-rm-sales-trx-add`, `dynamics-gp-rm-customer-add`, `dynamics-gp-gl-bank-deposit-add` or any other dynamics-gp write tool. The stripe server has no write tools.
* Payments are not posted here. A paid Stripe invoice goes in as an invoice only.

**Validation:**

* If every Stripe invoice is already in GP, say so and stop.
* If a Stripe number is longer than 21 characters, GP cannot hold it. Report it and do not post it.
* If a post fails, report the error, do not retry it, and continue with the next invoice.
* If the invoice currency is not the GP company's functional currency, do not post it. Report it instead.
