5d3c2e6f9a fix: filter physics volumes like the client's collision groups
Volumes on the server touched far more than in the client:

- An enemy's body in the physics world was a sphere the size of its aggro
  radius, so trigger and damage volumes caught enemies from far away
  (Cavalry Hill enemies taking damage on spawn). It is now the enemy's
  own radius and collision group from its physics component.
- Trigger volumes ignored their collision group and caught everything.
  dpEntity now filters with the client's collision filter
  (PeCollisionFilter, 1.10.64 0x00fb6940, group table from 0x00fcf9a0):
  POI walls ignore enemies, threat clearing walls ignore players, and
  so on. The aggro sensor keeps seeing only players.
- Rotated boxes were tested as the axis aligned box around them, which
  for a turned wall covers a big square (the AG survival boundary).
  Sphere and point tests now use the box's own axes.

Proximity monitors take an optional collision group like live's
SetProximityRadius; the AM shield generators use live's (10 finds
enemies, 1 finds players).

2d76c81bba feat: server side knockback for AI moved objects
The client only simulates knockbacks on the character it controls
(LWOControllablePhysComponent::msgKnockback); enemies and NPCs are drawn
where the server puts them, so a knockback on them did nothing and
scripts stunned them instead.

MovementAIComponent::Knockback now flies the object the way the client
flies its character: a vector longer than 5 lifts it 0.5, throws it with
that velocity under WorldConfig gravity (times its gravity scale) until
it lands on the navmesh, no sooner than 250ms later; a shorter one moves
it by the vector. Walls taller than a step stop sideways motion, the
landing is put back onto the navmesh, and pathing and the combat AI wait
until it lands (destinations set mid air are walked to afterwards).
Position and velocity go out in the normal serialization every tick.

KnockbackBehavior builds the vector like the client's Cast (strength
capped at 300, angle as elevation, relative, caster and ignore_self) and
knocks back server moved targets that aren't immune, both when the
server casts and when a client's skill hits. The blocked bit it writes
now also answers for the target's knockback immunity, so a player whose
client hasn't caught up with a Personal Fortress isn't knocked out of it.

The AM shield generators knock enemies back like live instead of
stunning them.

dae1925d1a refactor: effects, audio, animation and UI text game messages as structs
Converts PlayAnimation, PlayNDAudioEmitter, PlayEmbeddedEffectOnAllClientsNearObject,
PlayFXEffect, StopFXEffect, BroadcastTextToChatbox, Play2DAmbientSound,
Stop2DAmbientSound, UIMessageServerToSingleClient, UIMessageServerToAllClients,
StartCelebrationEffect, DisplayMessageBox, DisplayChatBubble, ChangeIdleFlags,
SetNameBillboardState, ShowBillboardInteractIcon, PlayCinematic, EndCinematic,
SlashCommandTextFeedback, PlayEmote and SetEmoteLockState (21 old Send
functions, 23 with overloads) and the received MessageBoxRespond,
ChoiceBoxRespond, CinematicUpdate and PlayEmote to NetGameMsgs in
EffectsMessages.{h,cpp}. The high traffic messages get a constructor for their
required fields. UI messages own their AMF arguments. Every caller is switched,
the received messages are registered in GameMessageHandler's map, and the old
functions and switch cases are deleted. Handlers are copied verbatim.

No wire change and no change in recipients: functions that always broadcast
whatever address they were given are sent with Send(UNASSIGNED_SYSTEM_ADDRESS),
functions that only did SEND_PACKET use SendToClient. Quirks are kept and
documented on the structs (PlayAnimation's UTF-8 sized name, the always written
null terminator in BroadcastTextToChatbox, StartCelebrationEffect always
writing celebrationID, SetNameBillboardState having no payload).

Verified byte for byte against a frozen verbatim copy of the old functions over
an input grid, to one client and broadcast; received messages compared with the
old handlers' read sequences and every truncated payload rejected; hand
computed golden bytes; round trips; a deliberate width mutation made the tests
fail. The byte-equality helper gains a Broadcast mode for functions that
ignored their address.

455f9470a5 Move EntityManager to Game namespace (#1140)
* Move EntityManager to Game namespace

* move initialization to later

Need to wait for dZoneManager to be initialized.

* Fix bugs

- Cannot delete from a RandomAccessIterator while in a range based for loop.

Touchup zone manager initialize

replace magic numbers with better named constants
replace magic zonecontrol id with a more readable hex alternative
condense stack variables
move initializers closer to their use
initialize entity manager with zone control

change initialize timings

If zone is not zero we expect to initialize the entity manager during zone manager initialization

Add constexpr for zone control LOT

* Add proper error handling

* revert vanity changes

* Update WorldServer.cpp

* Update dZoneManager.cpp
