/**
 * 作息报时器（schedule_reminder）后端接口集成测试
 * 独立起一个临时 express 实例（8978），只挂载 schedule_reminder 的路由，
 * 不依赖 8976 主服务，也不影响运行中的服务。
 *
 * 数据库隔离策略：脚本开始时若 data/app_order_box_schedule_reminder.db 不存在，
 * 结束时把测试期间产生的 db / wal / shm 一并删除，保证不留测试脏数据。
 *
 * 运行：node dev_test_scripts/integration/test_schedule_reminder_integration.js
