 *  - orderToVAIData: productTotal = tổng tiền SP (KHÔNG trừ phí); lấy notes từ order.notes (ưu tiên) rồi qd.notes
 *  - openOrderDetail: thêm cột Ghi chú vào bảng; lấy date từ input; luôn recalc trước export
 *  - parsePrompt: 'Malloca ck 35%' detected as global discount; 'ghi chú: giao thứ 7' = note
