feat: 新增作息报时器功能并替换短链接前缀为/to/

- 新增作息报时器独立模块，包含完整的日程管理、语音播报和待机功能
- 短链接正式前缀由/l/改为/to/，解决手机小屏下与I、i、1字形混淆问题
- 保留旧前缀/l/、/L/、/I/、/i/兼容已分发的旧短链
- 新增短码大小写兜底匹配，仅唯一匹配时生效避免歧义
- 新增防爆紧急替换功能，可轮换首页鉴权并替换短链接
- 新增多个调试和集成测试脚本，保障数据安全和功能回归

+/**
+ * 恢复被误删的作息日程（一次性数据恢复脚本）
+ *
+ * 背景：调试脚本的"清理"步骤误删了用户真实创建的日程。
+ * 作息日程的删除是**软删除**（schedules.deleted = 1），数据行与 items_json 都还在，
+ * 因此可直接把 deleted 改回 0 完成恢复，无需重建。
+ *
+ * 用法：
+ *   node dev_test_scripts/debug/tool_restore_deleted_schedule.js            # 列出所有已软删的日程
+ *   node dev_test_scripts/debug/tool_restore_deleted_schedule.js <scheduleId>  # 恢复指定 id
