定时下载(APScheduler) + 跑比对纯离线 + 偏移拆 expected/actual + 报告下载

定时下载：
- state_store：site_config 加 schedule_enabled/schedule_time（旧库迁移）+ set_schedule/get_all_config
- server：APScheduler BackgroundScheduler，启动按配置注册各站 cron job、改配置重排；job 投 undelivered 任务到队列（错过跳过）；/config 扩展 schedule
- runtime：("__compare__","compare") 改纯离线 expected_undelivered.main()（不下载）
- requirements：加 apscheduler

偏移拆分 + 报告下载：
- state_store：date_offset 拆 expected_offset/actual_offset（迁移）+ get_offset(site,kind)/set_offset(site,kind,n)
- 4 站 actual impl 改读 actual 偏移（expected 走默认 kind）
- server：/config 用 expected_offset/actual_offset；新增 GET /report（服务 output/应到未到数据.xlsx）
- paths：加 OUTPUT_DIR
