Converts ActivityEnter, ActivityExit, ActivityStart, ActivityStop,
ActivityPause, StartActivityTime, RequestActivityEnter,
RequestActivityExit and ShowActivityCountdown to NetGameMsgs in
ActivityMessages.{h,cpp}, switches their callers (racing, shooting
gallery, survival, waves, AG course, NT combat challenge) and deletes
the old GameMessages::Send* / HandleRequestActivityExit functions.
REQUEST_ACTIVITY_EXIT is registered in GameMessageHandler's map.
No wire change. Verified by comparing every struct byte for byte with a
frozen verbatim copy of the old functions (tests/.../Legacy) over a
grid of inputs, both to one client and as a broadcast (a temporary test
proved the copy matched production before it was deleted), plus hand
computed golden bytes, round trips and a deliberate field mutation that
made the tests fail. Layouts confirmed against the 1.10.64 client in
Ghidra. Only difference: a broadcast no longer makes
the extra Send(UNASSIGNED, false) that RakNet already rejected.

THIS CHANGES THE BYTES SENT TO THE CLIENT (intentionally).
UnSmash::Serialize wrote the "duration != 3.0f" flag but guarded the
value with "builderID != 3.0f" (a typo), so the 32-bit duration was
always written, even after a 0 flag. The LEGO Universe 1.10.64 client
(GameMessage::UnSmash::Serialize/Deserialize @ 00dc0e80/00dc0f50,
default 3.0f @ 017e66b4) writes it only when
duration != 3.0f. The client read the flag and ignored the trailing 32
bits, so this removes 4 junk bytes from default UnSmash messages;
messages with a non-default duration are unchanged.
Uses WriteOptional/ReadOptional and adds Deserialize. Verified with
hand computed golden bits for every flag combination and round trips.

First step of moving hand written bitstream code to struct based
messages (see docs/PacketArchitecture.md). No wire changes.
- GameMsg is now only a server-internal event (delivered to handlers
registered with RegisterMsg); NetGameMsg is a wire message with
Send(sysAddr) (UNASSIGNED broadcasts), SendToClient(sysAddr) (one
client, never broadcasts), WritePacket, Serialize, Deserialize and
Handle. Mixing them up is now a compile error. NetGameMsgEvent<T> /
DeliverLocally carry a wire message to local handlers; loot drops,
pickup, the object debugger, GM invisibility and model RequestUse
use them. The GM invisibility message keeps its target, so its bytes
are unchanged.
- Behaviour change: GameMessageHandler logs and drops messages whose
Deserialize fails instead of handling them with default fields (the
4 messages already registered: RequestUse, RequestServerObjectInfo,
ShootingGalleryFire, PickupItem).
- LUBitStream (kept as on main) gets a virtual destructor (Mail deleted
derived packets through the base) and WritePacket, also used by
ChatPackets::SendRoutedMsg with identical bytes.
- BitStreamUtils::WriteOptional/ReadOptional for default-flag fields
and WriteLengthPrefixed/ReadLengthPrefixed for length prefixed
strings.
- Every message ID enumerator (MessageType::*, ServiceType, Mail's
wire enums) is pinned with static_asserts, so renumbering or removing
one fails to compile.
- Tests: dServerMock copies each sent packet (it kept a pointer to the
caller's destroyed BitStream); PacketTestUtils.h compares packets bit
for bit; helper tests use hand computed golden bytes and equality
with the hand written patterns they replace; compile-time checks
keep the wire/internal split in place.
- docs/PacketArchitecture.md: survey, target architecture,
conventions, verification method and migration plan.

Brick building as of right now does not implement the undo action properly. This commit addresses the issue with undoing button being non-functional server side and implements the GM needed for addressing further issues.
Implement GameMessage UnUseModel which is called when a model in BrickBuilding is UnUsed. Important for UGC content down the line. Final code has been tested as follows:
1. Placed a model in brick build
2. saved placed a brick
3. repeat 2 and 3 twice more for 6 total models
4. Place a new model in brick mode and then edit all 7 models into one brick model instance
5. Pressing undo returns the converted model to the inventory and properly discards the other 6 without crashing. Intended live behavior is to store this in the inventory instead however behind the scenes work is needed to implement UGC models properly.
Implement enum
Implement the BlueprintSaveResponseType enum so there are less magic numbers sent via packets.
Correct int sizes from unsigned int to uint32_t
Add deserialize test
Add a test for de-serializing a GM that is sent to the client. Assertions verify the data is in the correct order and has no extra information.
