feat(jobs): Jobs.1 client UI infra (handler + library + tecla J) + UI tweaks

Infraestrutura cliente da promocao de classe (Jobs.1). WBP_JobChangePanel
NAO esta neste commit — foi exploracao descartada (criar UI dinamica de
botoes via MCP BP graph esbarrou em limites do CreateWidget node). A
fundacao C++ fica pronta pra ser usada quando voltarmos pra UI.

INFRA C++ NOVA (Source/ZMMOJobs/)
* UZMMOJobChangeNetworkHandler (WorldSubsystem novo) — bind no
  OnJobChangeResult do plugin e re-broadcast via FZMMOOnJobChangeResultBP
  (dynamic multicast assignavel em BP). WBP futura escuta direto.
* UZMMOJobsSubsystem helpers: GetJobsByTier(EZMMOJobTier) +
  GetEligibleNextJobs(currentClassId) — filtra por ParentClassId. Pure.
* UZMMOJobsLibrary BPFL wrappers + SendJobChangeRequest convenience
  (delega pro UZeusNetworkSubsystem). Dep ZeusNetwork adicionada no
  Build.cs.

ENUM + INPUT
* EZMMOInGameUIState ganha JobChangePanel (entre StatusWindow e
  Inventory). DA_InGameScreenSet pendente de receber entry quando
  WBP for criada (tecla J vai falhar silenciosamente ate la).
* ZMMOPlayerController: tecla J -> ToggleJobChangePanel ->
  Flow->ToggleScreen(JobChangePanel). Espelha pattern do Alt+A do
  StatusWindow (InputComponent legacy BindKey + FInputChord).

UI TWEAKS
* WBP_StatusWindow + DT_UI_Styles: ajustes visuais no Editor durante a
  sessao (sem mudanca funcional documentavel — provavelmente fontes/
  spacing/cores).
