feat(approvalFlow): P3-15 节点级统计 + 流程升级机制收尾 (triggerTimeoutScan); bump 2.4.81/1.0.48

P3-15 节点级统计
- 后端新增 FlowStatisticsService + FlowStatisticsDtos：概览卡片、日趋势、流程维度、节点维度（含最长/最短审批人）、审批人维度、TopN 最慢节点
- 筛选维度支持 BizType、发起人部门（InitiatorOrgIds）、日期区间、流程 Id
- 菜单种子新增"审批统计"页面（/aidop/flowManage/flowStatistics）
- 前端新增 statistics/index.vue：4 张卡片 + 日趋势折线 + TopN 最慢节点柱状 + 3 张表（流程/节点/审批人）
- 前端 api.ts 补齐 5 个统计接口绑定

流程升级机制收尾（Escalation）
- FlowEngineService 抽取 ScanTimeoutTasks(CancellationToken) 公共方法；FlowTimeoutJob 委托给该方法，避免扫描逻辑两处维护
- FlowTaskService 新增 POST /api/flowTask/triggerTimeoutScan，仅 SuperAdmin/SysAdmin 可调用，返回本次处理条数
- 同时满足运维排障与 E2E 自动化（绕开 1h 超时 + 5min 扫描周期的等待）

验证
- _verify_escalation.py 覆盖 4 种超时动作（Notify/AutoApprove/AutoReject/AutoEscalate）+ 手动升级 + 管理员权限校验，22/22 PASS
- _verify_statistics.py（上一轮）14/14 PASS
- 后端 build 0 error

文档
- doc/plan/审批流-流程升级机制实施方案.md：验收标准勾选 + 新增"九、收尾验证"
- doc/plan/审批流-综合优化方案.md：第五批勾选"节点级统计"与"流程升级机制收尾"

+
+## 九、收尾验证（2026-04-17）
+
+### 9.1 为什么需要专门"收尾"
+
+本方案 Step 1~6 的代码实现在 2026-04-16 已全部合入（见 `git log` v1.0.48 相关提交）。但超时自动处理的特性决定了它难以在开发期验证——最短 `timeoutHours=1` 小时、`FlowTimeoutJob` 每 5 分钟扫描一次，E2E 自动化等不起。
+
+因此本次收尾的核心，是把"扫描动作"从 Job 独占中解耦，让运维/自动化脚本能立刻触发一次。
+
+### 9.2 本次新增的最小改动
+
+| # | 文件 | 动作 | 目的 |
+|---|------|------|------|
+| 1 | `Service/FlowEngine/FlowEngineService.cs` | 新增 `ScanTimeoutTasks(CancellationToken)` 公共方法 | 把扫描逻辑从 Job 抽出成服务层公共方法，返回实际处理条数 |
+| 2 | `Job/FlowTimeoutJob.cs` | 重构：委托给 `engine.ScanTimeoutTasks()` | 单一数据源，避免扫描逻辑两处维护 |
+| 3 | `Service/FlowTask/FlowTaskService.cs` | 新增 `POST /api/flowTask/triggerTimeoutScan` | 仅 SuperAdmin/SysAdmin 可调用；返回本次处理条数；用于运维排障与 E2E |
+| 4 | `_verify_escalation.py`（仓库根）| 新增 E2E 脚本 | 覆盖 4 种超时动作 + 手动升级 + 管理员权限校验 |
+
+### 9.3 E2E 验证结果
+
+运行 `python _verify_escalation.py`（后端 1.0.48 已启动）：
+
+```
+PASS: 22 / TOTAL: 22
+```
+
+覆盖断言（22 项）：
+
+- Notify：任务保持 Pending + 写入 `AutoTimeout(10)` 日志 + 二次扫描幂等不重复写
+- AutoApprove：任务变 `Approved(1)`、实例变 `Approved(2)`、日志含 `AutoTimeout`
+- AutoReject：任务变 `Rejected(2)`、实例变 `Rejected(3)`、`EndTime` 写入
+- AutoEscalate：原 task 变 `Escalated(6)`、给配置的升级目标生成新 Pending 任务、实例仍 `Running(1)`、日志含 `AutoTimeout`
+- Manual：`GetEscalationConfig` 返回 `enabled=true`；调用 `Escalate` 后原 task `Escalated`、目标收到新 Pending、日志含 `Escalate(11)`
+- 权限：非管理员账号（`AccountType=NormalUser`）调用 `triggerTimeoutScan` 返回 400 且 message 明确提示"仅超级管理员/系统管理员可触发该操作"
+
+### 9.4 运维使用方式
+
+```bash
+# 以 SuperAdmin/SysAdmin 身份获取 token 后：
+curl -X POST https://<host>/api/flowTask/triggerTimeoutScan \
+     -H "Authorization: Bearer <token>"
+# 返回值为本次处理的超时任务条数（int）
+```
+
+### 9.5 未改的部分
+
+- `FlowTimeoutJob` 触发周期仍为 5 分钟，未改动调度参数。
+- 所有状态机/通知/日志行为与 Step 1~6 版本一致。
+- 数据库表结构不变。
