fix(net): D.2b-B B-Wire — ParsePutObjInContainer reads containerType (4th field)

Browse source 
0x0022 InventoryPutObjInContainer carries 4 u32s per ACE
GameEventItemServerSaysContainId.cs: itemGuid, containerGuid, placement,
containerType. The parser was reading only 3 (12 bytes) and silently
dropping containerType. Fixed the record struct to add ContainerType and
raised the length guard to 16. GameEventWiring caller uses only
.ItemGuid/.ContainerGuid/.Placement — adding a positional field is
source-compatible. 1 new test in GameEventsInventoryTests.
