feat(attributes): cliente Fase 1 — sub-modulo ZMMOAttributes + HUD HP/SP

Browse Source 
Espelho do AttributeSystem do servidor (Game/MMO/Modules/AttributeSystem).
Sub-modulo C++ Source/ZMMOAttributes/ (Runtime, LoadingPhase=PreDefault)
isolando o cliente do AttributeSystem em pasta propria — pavimentando o
caminho para futuros Inventory/Skills/Combat virem como sub-modulos peer.

Componentes:
  - FZMMOAttributesSnapshot (USTRUCT Blueprint, espelha
    FZeusAttributesPayload do plugin ZeusNetwork)
  - UZMMOAttributeComponent (UActorComponent ligado ao player):
    ApplySnapshot / ApplyHpSpUpdate / NotifyLevelUp + 3 delegates
    dinamicos (OnAttributesChanged / OnHpSpChanged / OnLevelUp) +
    helpers GetHpRatio / GetSpRatio
  - UZMMOAttributeNetworkHandler (UWorldSubsystem): ponte
    UZeusNetworkSubsystem -> componente via lookup por EntityId
  - UZMMOHudHpSpWidget (UUserWidget base): BindWidget (HpBar, SpBar) +
    BindWidgetOptional (HpText, SpText, LevelText). NativeConstruct
    binda nos delegates do componente; NativeDestruct desliga.
    OnSnapshotApplied / OnHpSpDelta (BlueprintNativeEvent) com impl
    C++ atualizando progress bars e textos.

Integracao no PlayerCharacter:
  - CreateDefaultSubobject<UZMMOAttributeComponent> no ctor
  - HudHpSpWidgetClass (TSubclassOf) resolvido via
    ConstructorHelpers::FClassFinder em /Game/ZMMO/UI/HUD/WBP_HUD_HpSpBar
  - HandleLocalSpawnReady seed do EntityId no componente + spawn do HUD
    (CreateWidget + AddToViewport + BindToAttributeComponent)
  - EndPlay remove widget do parent

WBP_HUD_HpSpBar (UMG, criado via MCP):
  - Overlay root + SizeBox (320x120) + VerticalBox
  - 5 widgets BindWidget: LevelText, HpBar (vermelho), HpText,
    SpBar (azul), SpText
  - Herda de UZMMOHudHpSpWidget

Verificacao (smoke test):
  - PIE login -> server envia S_ATTRIBUTE_SNAPSHOT_FULL
  - Cliente recebe via OnAttributeSnapshotFull -> handler roteia pra
    componente do entity -> ApplySnapshot dispara OnAttributesChanged ->
    widget atualiza ProgressBars + TextBlocks
  - HUD aparece no canto inferior esquerdo da tela com valores
    correspondentes ao DB
