feat(frontend): Fase 1 + 1.5 — ServerSelect dinamico + Lobby (chars por mundo)

ServerSelect (Fase 1):
- UIServerSelectScreen_Base: subscribe OnRawMessage + C_WORLD_LIST_REQUEST
- WBP_ServerCard instanciado dinamicamente em GridPanel CardContainer (2 cols)
- UIServerCard_Base: SetFromEntry + OnCardPressed delegate + UI_Button_Master
- Push real-time S_WORLD_STATUS_UPDATE (opcode 2062) atualiza card in-place
- FZMMOWorldEntry struct, EZMMOWorldState enum no wire (offline/online/maint)
- Sem hardcap de slots — cards usam toda largura via ColumnFill weights

Lobby/CharSelect (Fase 1.5):
- UIUserLobbyScreen_Base + WBP_UserLobby (WidgetSwitcher: lista + create)
- C_CHAR_LIST_REQUEST filtrado por SelectedWorldId do FlowSubsystem
- UICharCard_Base + WBP_CharCard com Select/Delete + Accept/Cancel quando
  delete agendado; Text_DeleteCountdown atualiza em tempo real (timer 1s)
- UICharacterCreatePage_Base + WBP_CharacterCreate (Name + ComboBox class)
- Handlers S_CHAR_SELECT_OK (handoff parse), CHAR_CREATE_OK/REJECT,
  CHAR_DELETE_ACK/ACCEPT_ACK/CANCEL_ACK (refresh lista)

Auxiliares + fixes:
- ARQUITETURA_SERVER_SELECT.md + ARQUITETURA_CHARACTER_MODEL.md
- UIFrontEndFlowSubsystem: SelectedWorldId state + transicao Lobby
- DA_FrontEndScreenSet: Lobby -> WBP_UserLobby_C
- UICheckBox_Base + UICommonText_Base (componentes auxiliares)
- BSB_Button_Transparent.Disabled DrawAs=IMAGE -> NoDraw (fix bg branco)
- WBP_ServerCard layout: HBox para chips Region/Ping/Status, SizeBox 10x10
  no Dot verde (anti-overflow); SelfHitTestInvisible em containers (hover)
