fix: 修复定时任务模块问题

1. 修复 SDK 文档 API 路由顺序问题
   - 将静态路由 /sdk-docs, /test-script, /secrets 移到动态路由 /{task_id} 之前
   - 解决 "请求参数验证失败" 错误

2. 优化错误页面体验
   - 使用 sessionStorage 传递错误信息，URL 保持干净
   - 使用 router.replace 替代 push，浏览器返回不会停留在错误页
   - 记录来源页面，支持正确返回

3. 增强网络错误处理
   - 区分超时、网络错误、服务不可用
   - 后端未启动时显示友好的 "服务暂时不可用" 提示

4. 添加定时任务模块文档

+# 定时任务系统文档
+
+## 功能概述
+
+平台定时任务系统，支持 Python 脚本或 Webhook 定时执行，执行结果可自动推送到钉钉/企微机器人。
+
+**核心能力**：
+- 脚本执行：安全沙箱运行 Python 脚本，内置 AI、HTTP、数据库等 SDK
+- 调度方式：指定时间点（多选）或 CRON 表达式
+- 消息推送：支持钉钉/企微机器人所有消息格式（markdown、actionCard、feedCard 等）
+- 失败处理：支持重试和告警通知
