问题：app.py:auto_monitor_job（定时）和 routes/api.py:run_monitor（手动） 各自维护了一份几乎相同但细节不一致的写入逻辑，同一条数据经不同入口落库后 latest_time / source / offset / file_count 可能不同。 - 新增 services/time_utils.py：calculate_offset 下沉到无依赖模块，避免 db_ingest 与 routes.api 互相 import 形成循环。routes/api.py 里 re-export 一次，保证 app.py 原有的 from routes.api import calculate_offset 不失效。 - 新增 services/db_ingest.py:ingest_device_data()，承载全部入库细节，只 add/flush 不 commit，事务边界交给调用方。 - routes/api.py:run_monitor 瘦身为「触发爬虫 -> 调管道 -> 提交」。 - models.py:to_dict() 的 offset 改为读取时用 calculate_offset(latest_time) 实时计算，不再读 offset 列。该列是写入时刻的快照，采集一停摆就整体失真 （库里停在 2026-02-06，offset 却仍显示“当天”）。列保留但已废弃， 不执行 ALTER TABLE DROP COLUMN。 入库语义（db_ingest）： - 只有爬虫拿到真实业务时间才更新主表 latest_time，拿不到就保留上一个有效值 （冻结），不再回退到 current_time。 - DeviceHistory 单独用 history_time：主表回答“数据到什么时候”，历史回答 “什么时候采过”。 - 历史表 json_data 改存本次增量切片，不再复制主表那份越滚越大的累积 JSON。 - 主表 json_data 改为覆盖式更新以切断无限膨胀，但保留 APP_OWNED_KEYS （bound_iccid / is_whitelist）—— 这两个键由 /bind_device_card 和 /toggle_whitelist 写入，按原方案直接覆盖会清空所有设备-流量卡绑定。
