DarkflameServer/dGame/dGameMessages/PropertyMessages.cpp
Aaron Kimbrell 9458230f0b refactor: property game messages as structs 
Converts the property messages to NetGameMsgs in PropertyMessages.{h,cpp}.
Sent: OpenPropertyVendor, OpenPropertyManagement, DownloadPropertyData
(replaces PropertyDataMessage, now with the client's PropertyData field
names), PropertyRentalResponse, PropertyEntranceBegin,
PropertySelectQuery (replaces PropertySelectQueryProperty with the
client's PropertyInfo), GetModelsOnProperty, PlaceModelResponse and
HandleUGCEquipPre/PostDeleteBasedOnEditMode. Received, registered in
GameMessageHandler's map: SetPropertyAccess,
UpdatePropertyOrModelForFilterCheck, QueryPropertyData,
PropertyEditorBegin/End, PropertyContentsFromClient,
ZonePropertyModelEquipped/Rotated, PlacePropertyModel,
UpdateModelFromClient, DeleteModelFromClient, ControlBehaviors,
PropertyEntranceSync, EnterProperty1, UpdatePropertyPerformanceCost,
ReportOffensiveModel/Property and GetHotPropertyData. The news screen's
NewsSendHotPropertiesInfoToClient moves here with the top properties
lookup; the dashboard's player reports now take the decoded text.

Handlers keep their logic and hand the work to PropertyManagementComponent,
PropertyVendorComponent, PropertyEntranceComponent and
MultiZoneEntranceComponent as before. Messages whose payload DLU ignored
(PropertyEditorBegin, PropertyContentsFromClient, ZonePropertyModel*)
now read it with the client's layout. The never-called
SendZonePropertyModelEquipped (which wrote no default flags) is gone.

No wire change and no change in recipients. Verified byte for byte
against a frozen verbatim copy of the old functions, PropertyDataMessage
and PropertySelectQueryProperty over an input grid (to one client and
broadcast), received messages compared with the old handlers' read
sequences with every truncated payload rejected, hand computed golden
bytes, round trips and a mutation check. Layouts confirmed against the
1.10.64 client in Ghidra. Known wire bug kept as is: PlaceModelResponse
writes response where the client reads a rotation quaternion
(PlaceModelResponse::Deserialize 0x00dc0170).
