370a03f0a3 refactor: remove the packet macros, WriteHeader and PacketUtils
Nothing in the server writes or reads a packet by hand any more, so the
helpers for doing so go:
- CBITSTREAM, CMSGHEADER, CINSTREAM, CINSTREAM_SKIP_HEADER, SEND_PACKET,
  SEND_PACKET_BROADCAST and HEADER_SIZE leave dCommonVars.h;
- the free BitStreamUtils::WriteHeader (LUBitStream::WriteHeader writes the
  same bytes) and the unused PacketUtils::SavePacket are deleted.
The last raw reads are replaced: WorldServer builds its input stream
directly, the master packet logs read the header with
LUBitStream::ReadHeader instead of peeking at packet->data[1] and [3], and
MessageInspector reads a sent game message's header with the new
NetGameMsg::ReadPacketHeader (the counterpart of WritePacket) instead of
memcmp/memcpy. packet->data[0] is still compared with RakNet's own
connection IDs.

The frozen oracles keep using the macros verbatim through the test-only
tests/dGameTests/LegacyPacketMacros.h; the HeaderSkip tests, which only
tested CINSTREAM_SKIP_HEADER, are removed.

docs/PacketArchitecture.md: "where we are" now describes the final state
and what still touches raw bytes (RakNet IDs, replica headers, behavior bit
streams), and a new section collects the known wire discrepancies found
during the conversion, with client addresses.

1e4df609b0 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).
