feat: add item stack splitting via Shift+right-click

Browse source 
Implements CMSG_SPLIT_ITEM (0x10E) with a slider popup for choosing
split count. Auto-finds empty destination slot across backpack and bags.
Shift+right-click on stackable items (count > 1) opens split dialog;
non-stackable items still get the destroy confirmation.
