权限系统迁移完成：接口级权限 + 前置权限检查

## 核心改进
- 完全迁移到接口级权限（68个API端点）
- 实现前置权限检查机制，解决跨模块数据访问权限问题
- 添加权限管理API端点，支持前置权限查询

## 关键变更
1. 权限配置系统
   - 添加OPERATION_PREREQUISITES映射表
   - 所有操作配置前置权限依赖

2. 权限检查函数
   - role_has_api_permission()支持前置权限检查
   - get_missing_prerequisites()获取缺失权限列表

3. 权限管理API
   - GET /api-permissions/operations - 获取所有操作及前置权限
   - GET /api-permissions/operations/prerequisites - 获取前置权限依赖
   - GET /api-permissions/{endpoint_key}/prerequisites - 检查缺失权限

4. API端点迁移
   - 第1批：subjects, visits, aes, monitoring_visit_issues (23个)
   - 第2批：members, sites, project_milestones (11个)
   - 第3批：finance_contracts, fees_contracts, drug_shipments (15个)
   - 第4批：startup endpoints (19个)

## 测试验证
- 单元测试：24个测试全部通过
- 集成测试：22个迁移端点测试通过
- 前置权限测试：12个测试全部通过
- 总计：46个测试全部通过

## 向后兼容性
- 模块级权限表保留用于历史数据
- 接口级权限未配置时自动回退到模块级权限
- 现有权限配置继续有效
