feat(energy): 电能统计切到 bi_ele_charge_record，外部数据接通

- /api/energy/electric/overview & /electric/monthly 不再读 tab_energy_electricity_bill
- 改读 bi_ele_charge_record：kwh/fee/start_time
- 外部/我司用 vehicle_kind 区分（external/internal）
- 电能默认 customer 由 'external' 改 'lingniu'，与导入页约定一致
- ElectricDaily 移除「数据对接中…」友好空状态（外部已有数据）

ele 导入页同步收紧：
- 命中系统车辆=internal，未命中（含车牌为空）一律 external
- 移除 unknown 分类、KPI 卡、批次列、过滤按钮、UploadResult 字段
- 历史 unknown 行已 UPDATE 为 external
