Enter Sage Intacct sales orders with credit and stock checked

**Objective:** Create a {transaction-type} (default Sales Order) in Sage Intacct for the customer `{customer}` with these items: {items}. Add the customer PO number {customer-po-number} if one was given. Check the customer and items first, and get the user's confirmation before writing.

**Step 1: Resolve the customer**

Call `intacct-get-customer` with `customer-name.contains`, or with `customer-id` if the input looks like an ID.

* Several matches: list them and stop.
* Not active (`status`): stop and say so.
* `credit-limit` above zero, and `total-due` plus this order would exceed it: warn in the confirmation.

**Step 2: Resolve the items**

The create tool takes at most two lines. If more than two items were asked for, stop and say so, and offer to split them across documents.

For each item call `intacct-get-item` with `item-id`, then with `item-name.contains` if that finds nothing. Each must resolve to exactly one active item. Note `base-price` and `uncommitted`, and warn when `uncommitted` is below the quantity asked for.

**Step 3: Check the transaction type**

The transaction type must match a transaction definition name exactly. Call `intacct-get-order-entry-document` with `transaction-type` set to it and `max-records` 1. If nothing comes back, call it again without that filter and with `document-date.from` 90 days ago, list the `transaction-type` values in use, and ask which to use.

**Step 4: Confirm**

Show the draft: customer name and ID, transaction type, date (today unless the user gave one), each line's item ID, name, quantity and price, an estimated total, the PO number, and any credit or stock warning. Prices are `base-price` unless the user gave one; say the customer's price list may change them. Wait for an explicit yes.

**Step 5: Create**

Call `intacct-create-order-entry-document` once with `customer-id`, `transaction-type`, `date` as an ISO date, `item-id` and `quantity`, plus `item-id-2` and `quantity-2` for a second line, and `customer-po-number` and `due-date` when given. Pass `price` or `price-2` only when the user gave a price; otherwise leave it blank so the price list applies.

**Step 6: Verify and report**

Take the `document-id` from the response. Call `intacct-get-order-entry-document` with it for `document-number`, `state` and `total`, and `intacct-get-order-entry-document-line` with it to confirm the lines. Report the document number, total and lines.

**Rules & Guidelines:**

* The only write is `intacct-create-order-entry-document`, called once, after the user confirms. If it fails, report the error and do not retry with changed values unless the user asks.
* Do not call `intacct-create-customer` to create a missing customer, or `intacct-update-order-entry-document` to correct the result. Stop and tell the user instead.
* If the user names an Intacct company, pass it as `company` on every call.

**Validation:**

* If the customer or an item is not found, stop and say which.
* If a quantity is missing or not a positive number, ask for it.
