权限系统：完成接口级权限系统第6阶段（测试与文档）

## 主要完成内容 ### 1. 接口级权限系统实现 - 新增 ApiEndpointPermission 模型：存储接口级权限配置 - 新增 ApiEndpointRegistry 模型：注册系统中所有API端点 - 实现权限检查优先级：接口级 > 模块级（向后兼容） - 支持细粒度权限控制（METHOD:/path 格式） ### 2. 权限配置系统 - 创建 api_permissions.py：集中管理接口权限配置 - 定义 API_ENDPOINT_PERMISSIONS：所有端点的权限映射 - 定义 MODULE_TO_ENDPOINTS：模块到接口的映射（向后兼容） - 支持默认角色配置和权限继承 ### 3. 权限检查依赖注入 - 新增 require_api_permission()：基于接口的权限检查 - 新增 @register_api_endpoint 装饰器：端点元数据注册 - 集成 FastAPI 依赖注入系统 - 支持权限拒绝时返回 403 Forbidden ### 4. API端点迁移（第1批） - 迁移 subjects 模块：5个端点 - 迁移 risk_issues 模块：3个端点 - 迁移 fees 模块：8个端点 - 迁移 finance_contracts 模块：5个端点 - 共计 21 个端点完成迁移 ### 5. 权限管理API - GET /studies/{study_id}/api-permissions：获取权限矩阵 - PUT /studies/{study_id}/api-permissions：更新权限矩阵 - 支持权限配置的查询和修改 ### 6. 测试与验证 - 单元测试：12 个测试用例，全部通过 - 集成测试：11 个权限管理API测试，全部通过 - 端点测试：22 个已迁移端点测试，全部通过 - 代码覆盖率：87%（超过 80% 目标） - 总计：45 个测试用例，全部通过 ### 7. 文档 - TESTING_SUMMARY.md：详细的测试结果总结 - IMPLEMENTATION_SUMMARY.md：实现细节文档 - TESTING_GUIDE.md：测试指南 ## 技术亮点 1. **向后兼容性**：保留模块级权限，接口级权限优先 2. **灵活的权限配置**：支持默认角色和自定义权限 3. **细粒度控制**：支持跨模块数据访问权限 4. **完整的测试覆盖**：单元测试、集成测试、端点测试 5. **清晰的权限检查流程**：接口级 → 模块级 → 拒绝 ## 下一步工作 - [ ] 第7阶段：迁移第2批模块（members, sites） - [ ] 第8阶段：迁移第3批模块 - [ ] 第9阶段：安全审计 - [ ] 第10阶段：性能测试 - [ ] 第11阶段：文档更新 Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
