refactor(energy): 电能整体页面对齐氢能：每日 / 总览 子 tab 切换

- ElectricView 改为受控组件接收 sub prop（与 HydrogenView 对齐）
- EnergyModule sticky 头部统一显示 sub-tabs：氢能、电能都给 每日 / 总览
  ETC 仍不显示子 tab（建设中页）
- 共享 sub state 抽 helper：activeTab 切换时自动用对应的 sub
- 龙王路停车场充电站信息条移入 ElectricOverview 顶部（同氢能"数据自..."）

进入电能默认显示「每日」（与氢能一致），切换「总览」看 KPI + 柱图
