Undo a mistaken drop-ship (vendor-shipped) receipt

DROP-SHIP guided undo (2026-07-11, D9/F5). Reverses a mistaken “Mark shipped by vendor” event: reverses the drop-ship COGS + revenue/tax/shipping/discount recognition journal entries via linked reversal entries, voids the auto-created invoice and rebalances AR, rolls the sales order + purchase order quantities and statuses back, and removes the vendor shipment package (tracking preserved in the audit log). The already-sent customer shipment email cannot be unsent; the response surfaces customer_email_already_sent and a suggested follow-up (never auto-sent). Blocked when a vendor bill, a payment, or a return references the receipt, or the receipt is not the sole fulfillment event on a pure drop-ship order (see the eligibility preview). Requires purchasing:write.
