feat(energy): 用 truck_id 区分外部/我司，外部数据空时给友好提示

- 后端 customerClause 改为基于 truck_id：外部=IS NULL，我司=IS NOT NULL
- KPI 内联条件（ourYearKg/Fee、customerYearKg、lingniuBornKg/Fee）同步切换为 truck_id
- 调用方 /hydrogen/daily 与 /electric/monthly 改传 b.truck_id / truck_id
- 当前外部账单 truck_id 尚未对接，HydrogenDaily/ElectricDaily 在 customer=external 且无数据时
  改展示「数据对接中…」友好状态（插头图标 + 蓝色脉冲），替代「暂无数据」
