+/**
+ * V.AI STUDIO — ULTIMATE FIX v1100 (FINAL)
+ * 
+ * ===== VẤN ĐỀ =====
+ * 1. _doExportExcel trong qr-payment.js tạo blob URL và revoke sau 60s → không tải lại
+ * 2. 3 file fix cũ (v1042, robust-v2, multi-download) ghi đè lẫn nhau → conflict
+ * 3. Nut Excell/PDF trên modal không bind đúng hoặc bị ghi đè nhiều lần
+ * 4. Window._vaiExportCache bị các file fix cũ ghi đè sai → không tìm thấy file đã xuất
+ * 
+ * ===== FIX TRIỆT ĐỂ =====
+ * 1. Intercept URL.createObjectURL + URL.revokeObjectURL — GIỮ blob VĨNH VIỄN
+ * 2. Lưu tất cả blob export vào _vaiFinalExportStore (dùng array, ko dùng object dễ bị ghi đè)
+ * 3. Thêm UI "Tải lại file đã xuất" vào cả modal báo giá và modal chi tiết đơn hàng
+ * 4. Bind trực tiếp các nút export (ko qua trung gian)
+ * 5. Xuất lại file mới nếu blob cũ không còn (tự động fallback)
