Fix missing armor in WotLK item tooltips and character stats

SMSG_ITEM_QUERY_SINGLE_RESPONSE in WotLK 3.3.5a sends BuyCount as a
separate field before BuyPrice. The parser was skipping only one of the
two fields, shifting every subsequent read by 4 bytes. This caused
statsCount to be read from ContainerSlots (always 0 for non-bags) so
no stat pairs were parsed, and the armor field was read from the wrong
offset in the damage block — leaving all stat bonuses and armor at 0.

Also moved armor above stat bonuses in the item tooltip to match WoW's
canonical tooltip layout (armor, then green stat lines).
