cleanup: 历史记录从JSON迁移到DB(health_check_log表)

- 移除health_check_history.json → health_check_log表
- 移除health_known_issues.json（未使用）
- 移除TODO_PATH（已用DB替代）
- 更新文档注释

 """morning_health_check.py — MoFin 系统常规体检
 
 每日开盘前(8:00)运行，全面扫描MoFin所有组件健康状况。
+当前8类48项（清单自动扩展）。
 输出格式化的体检报告，有问题才出声，没问题静默。
 
 核心设计：
-  1. 从 health_checklist.json 读检查清单
-  2. 逐项检查，记录状态
-  3. 报告异常项（只推异常，不推正常）
-  4. 自动发现新增cron/脚本（通过 self_discovery 函数）
-  5. 维护检查历史 (health_check_history.json)
