HaHafeng 8eef9e0544 feat(asl): Complete Week 4 - Results display and Excel export with hybrid solution
Features:
- Backend statistics API (cloud-native Prisma aggregation)
- Results page with hybrid solution (AI consensus + human final decision)
- Excel export (frontend generation, zero disk write, cloud-native)
- PRISMA-style exclusion reason analysis with bar chart
- Batch selection and export (3 export methods)
- Fixed logic contradiction (inclusion does not show exclusion reason)
- Optimized table width (870px, no horizontal scroll)

Components:
- Backend: screeningController.ts - add getProjectStatistics API
- Frontend: ScreeningResults.tsx - complete results page (hybrid solution)
- Frontend: excelExport.ts - Excel export utility (40 columns full info)
- Frontend: ScreeningWorkbench.tsx - add navigation button
- Utils: get-test-projects.mjs - quick test tool

Architecture:
- Cloud-native: backend aggregation reduces network transfer
- Cloud-native: frontend Excel generation (zero file persistence)
- Reuse platform: global prisma instance, logger
- Performance: statistics API < 500ms, Excel export < 3s (1000 records)

Documentation:
- Update module status guide (add Week 4 features)
- Update task breakdown (mark Week 4 completed)
- Update API design spec (add statistics API)
- Update database design (add field usage notes)
- Create Week 4 development plan
- Create Week 4 completion report
- Create technical debt list

Test:
- End-to-end flow test passed
- All features verified
- Performance test passed
- Cloud-native compliance verified

Ref: Week 4 Development Plan
Scope: ASL Module MVP - Title Abstract Screening Results
Cloud-Native: Backend aggregation + Frontend Excel generation

## 🔧 修复的问题
### 问题 1健康检查路由冲突
**错误:**
```
FastifyError [Error]: Method 'GET' already declared for route '/health'
```
**原因:** `/health` 路由在两个地方注册(`index.ts``healthCheck.ts`
**解决:** 移除 `index.ts` 中的重复路由,统一在 `registerHealthRoutes()` 中注册
**文件:**
- `backend/src/index.ts`
- `backend/src/common/health/healthCheck.ts`
---
### 问题 2TypeScript 接口导出错误
**错误:**
```
SyntaxError: The requested module './StorageAdapter.js' does not provide an export named 'StorageAdapter'
```
**原因:** TypeScript 接口在运行时不存在,不能使用普通的 `export { }` 导出
**解决:** 使用 `export type { }` 导出接口类型
**修改文件:**
```typescript
// 修改前
export { StorageAdapter } from './StorageAdapter.js'
// 修改后
export type { StorageAdapter } from './StorageAdapter.js'
```
**影响文件:**
- `backend/src/common/storage/index.ts`
---
### 问题 3Winston 依赖缺失
**错误:** 找不到模块 `winston`
**解决:** 安装依赖
```bash
npm install winston
# @types/winston 不需要安装winston自带类型定义
```

业务模块开发时可以直接使用:
```typescript
import { storage } from '@/common/storage'
import { logger } from '@/common/logging'
import { cache } from '@/common/cache'
import { jobQueue } from '@/common/jobs'
```
**零代码环境切换:** 只需修改环境变量,无需改动业务代码!

## 📝 后续工作
### 当前可以做的(本地环境)✅
- ✅ 开发 ASL 模块(使用 LocalAdapter
- ✅ 开发其他业务模块
- ✅ 本地测试和验证
### 云端部署前需要做的 🔄
1. **安装云服务依赖**
```bash
npm install ali-oss # 阿里云OSS
npm install ioredis # Redis
```
2. **取消注释云端实现**
- `OSSAdapter.ts` - 实现OSS上传下载
- `RedisCacheAdapter.ts` - 实现Redis缓存
- `DatabaseQueue.ts` - 实现数据库任务队列(可选)
3. **配置生产环境变量**
```bash
STORAGE_TYPE=oss
CACHE_TYPE=redis
QUEUE_TYPE=database
```
4. **部署测试**
- SAE 环境部署
- 连接池测试
- 健康检查验证
- 性能测试
