feat(sync): synchronize customer orders from Hiboutik sales

For each customer sale not yet stored as completed, fetch the full sale
(GET /sales/:id) and upsert it as a STORE order keyed on hiboutikSaleId.
Lines are replaced on each upsert and linked to the matching product
version when it still exists. Quotations are skipped, orders are never
deleted.
