Subject: [PATCH] fix: increment new box number from max box number after
 completing current box

Unify optimization for single-code and multi-code boxing modes: after
completing a box, set the next box number to max(existing boxes) + 1,
avoiding duplicate box numbers when browsing historical boxes.
