Update order tags from line items for order routing

Line-item properties often lack sales-rep or VAT values, causing routing mistakes and invoice delays. Parsed tags are added to each order record so fulfillment and billing can act same day.

Overview

Unstructured line-item properties leave orders missing sales-rep or VAT context, forcing fulfillment and billing into manual lookups. This flow parses those properties and writes tags back to the order so ops and accounting can route and invoice the same day.
