Etsy: tracking sync now uses the receipt ID

What changed?

When sending tracking data to Etsy, Kiero OMS now uses the receipt identifier that is available on an imported order. An existing order with a saved shipment number can therefore start the tracking synchronization correctly.

Benefit

Tracking can reach Etsy even when the local record has no value in the auxiliary external_id field. Etsy buyers have a better chance of seeing the correct delivery information without manual copying.

How to use it

After creating a label for an Etsy order, leave the normal shipment synchronization enabled. Kiero OMS uses the receipt ID to create the job and sends the carrier and tracking number when shipment data is available.

Important limitations

The change requires deployment. Re-sending tracking for an existing order should be controlled after checking its data, to avoid duplicate operations. Carrier availability and tracking format still depend on Etsy requirements.
