-- =============================================================================
-- IT-7 叫乘记录三时间字段（可重放）
-- 依据：叫乘任务要求「每条记录包含 叫乘时间 / 复叫时间 / 应离寓时间」，
--       到点分别触发：首轮呼叫、自动复叫、离寓报警。
-- 口径：
--   1) jcsj 已存在（叫乘时间，权威）；本次只补 fjsj（复叫时间，计划）与
--      ylysj（应离寓时间）；
--   2) fjsj 与既有 fjsj_s 分工：fjsj=计划复叫时间（到点判定），
--      fjsj_s=实际复叫时刻（执行留痕，防重复触发）；
--   3) ryzt / finish_jc / finish_ly / stoped 仍只有 apt.duty.state 一个写入口，
--      本脚本不写任何业务数据；
--   4) 幂等：补列走 apt_add_column_if_missing，索引先查 information_schema。
