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

[bolg55]

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.

@khaliqgant I've made the requested updates from our Slack messages. Thanks

[khaliqgant]

Thanks! Looks good. You just need to bump the version of the action https://github.com/NangoHQ/integration-templates/blob/main/integrations/quickbooks/actions/create-invoice.ts#L22 so this version can be upgraded to and should be all set!

[bolg55]

@khaliqgant I've updated the version now, as requested for the create and update invoices actions.

[bolg55]

@khaliqgant Thanks for the approval! Looks like the CI workflows are still waiting for approval to run — would you mind approving those as well so the checks can complete?

[bolg55]

@khaliqgant Thanks - are you able to merge this 🙏
