feat(char-spawn): Fase 4 — DT_Maps + pawn reposicionado na pos do DB

Cliente UE (foco da frente):
- FZMMOMapDef + FZMMOMapSpawn (Source/ZMMO/Data/World/MapDef.h) — row do
  DT_Maps com MapId/DisplayName/ClientLevel/Spawns[] taggeados
- DT_Maps.uasset (Content/ZMMO/Data/World/) — 1 row "TestWorld" mapId=1
  apontando pra L_TestWorld + spawn "default" em (0,0,200)
- L_TestWorld movido: /Game/ThirdPerson/TestWorld -> /Game/ZMMO/Maps/World/L_TestWorld
  (75 ext actors WP duplicados, original deletado)
- ZMMOCharSummary.MapName (FString) -> MapId (int32)
- UIUserLobbyScreen_Base parseia uint16 mapId no S_CHAR_SELECT_OK + chama
  Flow->TravelToMapById(mapId) + Flow->SetPendingSpawnPose(pos, yaw)
- UIFrontEndFlowSubsystem: MapsTableAsset (config), FindMapDef,
  ResolveLevelPathByMapId, TravelToMapById, SetPendingSpawnPose/Consume
- AZMMOPlayerCharacter::BeginPlay: consome PendingSpawnPose do Flow e
  SetActorLocationAndRotation no pawn local (substitui PlayerStart default)
- DefaultGame.ini: MapsTableAsset=/Game/ZMMO/Data/World/DT_Maps.DT_Maps
- .gitignore: + .vscode/
