feat(quickbooks): add txn_date input to create-invoice action (#432)

## Summary
Adds support for setting the invoice transaction date (`TxnDate`) when
creating QuickBooks invoices.
## Problem
The `create-invoice` action currently doesn't allow setting the invoice
date (`TxnDate`). QuickBooks defaults to
today's date, which is incorrect when:
- Billing for past service periods (e.g., creating August invoices in
September)
- Invoice dates need to match billing cycles
The `txn_date` field is already mapped in the **output** (via
`toInvoice`), but cannot be set as **input**.
## Changes
- `schema.zod.ts`: Added `txn_date: z.string().optional()` to
`createInvoiceSchema`
- `mappers/to-invoice.ts`: Added mapping `txn_date` → `TxnDate` in
`toQuickBooksInvoice()`
- `actions/create-invoice.md`: Updated documentation
## Backward Compatibility
Fully backward compatible - `txn_date` is optional, existing
integrations unaffected.
