feat(调度任务): 实现调度任务管理功能

新增调度任务模块，支持任务的增删改查、启停及手动执行
- 后端添加 schedule_job 模型、服务、路由及调度器工具类
- 前端新增调度任务管理页面
- 修改 flow 相关接口将 id 类型从 String 改为 i64
- 添加 tokio-cron-scheduler 依赖实现定时任务调度
- 初始化时加载已启用任务并注册到调度器

+# Rust 代码风格规范（用于 AI 生成代码规则）
+
+## 1. 基础风格
+
+* 使用 **Rust 2021 edition**。
+* 缩进统一 **4 空格**，不使用 Tab。
+* 每行代码长度建议不超过 **100 字符**。
+* **花括号风格**：
+
+  ```rust
+  fn example() {
+      // good
+  }
+  ```
+* 表达式尽量简洁，必要时换行，参数链式调用时 **缩进对齐**。
+
+---
+
+## 2. 模块与导入
+
+* 模块顶部导入，按以下顺序分组，组间空一行：
+
+  1. **标准库 (`std::..`)**
+  2. **第三方库 (`chrono`, `sea_orm`, `tokio` 等)**
+  3. **本地 crate (`crate::..`)**
+* 统一使用 **显式导入**，禁止 `use super::*` 或 `use crate::*`。
+* 相同模块导入合并：
+
+  ```rust
+  use sea_orm::{EntityTrait, QueryFilter, ColumnTrait};
+  ```
+
+---
+
+## 3. 命名规则
+
+* **模块 / 文件名**：`snake_case`
+* **函数 / 变量名**：`snake_case`
+* **结构体 / 枚举名**：`PascalCase`
+* **常量**：`UPPER_CASE`
+* **DTO/请求体/响应体**后缀：`Doc` / `Req` / `Resp`
+
+示例：
+
+```rust
+pub struct ScheduleJobDoc { .. }
+pub struct CreateReq { .. }
+pub struct PageResp<T> { .. }
+```
+
+---
+
+## 4. 文档与注释
+
+* 每个 **模块** 顶部使用 `//!` 写模块职责说明。
+* 每个 **公开函数** 必须有 `///` 注释，简述用途与主要逻辑。
+* 内部复杂逻辑使用 `//` 单行注释解释。
+* 中文注释优先，避免英文缩写晦涩难懂。
+
+示例：
+
+```rust
+/// 创建任务：
+/// - 校验 cron 表达式
+/// - 校验唯一性
+/// - 入库后注册调度器
+pub async fn create(..) -> Result<..> { .. }
+```
+
+---
+
+## 5. 错误处理
+
+* 错误类型统一用 **自定义错误枚举**（如 `AppError`）。
+* 不直接 `unwrap()` / `expect()`，统一返回 `Result<T, AppError>`。
+* 错误信息应清晰且面向用户，内部日志保留技术细节。
+
+---
+
+## 6. 日志规范
+
+* 使用 `tracing` 库，必须带 `target`。
+* 统一格式：`模块.操作.状态`
+* 日志字段使用 `key = %value` 或 `key = ?value`，避免拼接字符串。
+
+示例：
+
+```rust
+info!(target = "udmin", id = %job_id, enabled = %enabled, "schedule_jobs.update.persisted");
+error!(target = "udmin", id = %job_id, error = %e, "schedule_jobs.run.failed");
+```
+
+---
+
+## 7. 异步与数据库
+
+* 使用 `async fn`，返回 `Result<T, AppError>`。
+* SeaORM 查询使用链式写法，**按字段过滤**时一行一个 filter。
+* 分页/排序明确写出，不隐式。
+
+示例：
+
+```rust
+let jobs = schedule_job::Entity::find()
+    .filter(schedule_job::Column::Enabled.eq(true))
+    .order_by_desc(schedule_job::Column::UpdatedAt)
+    .paginate(db, page_size);
+```
+
+---
+
+## 8. 结构体组织
+
+* DTO / 请求体 / 响应体 放在模块前部。
+* Service 函数按生命周期顺序：`list → create → update → remove → init`。
+* 工具函数（如 `build_executor_for_job`、`now_fixed_offset`）放在模块最后。
+
+---
+
+## 9. 闭包与异步执行器
+
+* 使用 `Arc::new(move || { Box::pin(async move { .. }) })` 形式。
+* 避免重复 clone，大对象提前 clone 一次再 move 进闭包。
+* 返回 `Pin<Box<dyn Future<Output = ()> + Send>>`。
+
+---
+
+## 10. 时间与 ID
+
+* 时间统一用 `chrono::Utc::now().with_timezone(&FixedOffset::east_opt(0).unwrap())`，可封装成 `now_fixed_offset()`。
+* ID 统一使用 `id: Set(crate::utils::generate_id())`。
+
+---
+
+## 11. 统一返回体
+
+* 分页接口统一返回 `PageResp<T>`。
+* 单条数据返回 DTO（如 `ScheduleJobDoc`）。
+* 删除接口返回 `Result<(), AppError>`。
+
+---
+
+## 12. 代码整洁性
+
+* 避免嵌套过深，必要时提前 `return`。
+* 冗余 clone 使用 `.clone()` 仅在必须时。
+* 枚举 / match 分支完整，必要时加 `_ => {}` 显式忽略。
+
+---
+
+⚡ 总结：
+生成的代码必须 **简洁、清晰、分组有序、日志一致、错误优雅**，看起来像经验丰富的 Rust 高手写的生产级代码。
