-- ICC 模拟量数据同步：重建 electricity_data 表结构（按 ICC AnalogInfoVO）
-- 1) 旧表无数据（0 行），直接 DROP 重建；2) 删除 equip_id/electricity、icc_device_code 更名 imei；
--   3) 新增 analog_type/analog_value；4) line_id 外键 → electric_line；5) 唯一键 (line_code,analog_type,collect_time)；
--   6) 按月分区 2026_10~2027_03；7) 索引/注释；8) sys_job 种子 icc_analog_sync（默认每 1 分钟）
