refactor: 全面清理项目结构，优化代码组织

主要改进：
1. 清理Core层空壳目录
   - 删除traits, transformers, query等空目录
   - 删除security, http, queue等空模块
   - 删除logger, context, exception等空壳

2. 清理Common层冗余模块
   - 删除utils, cache, queue等空壳模块
   - 删除dictionary, dict等重复字典模块
   - 删除重复的MemberModule.ts文件

3. 优化模块结构
   - 移动config到config/common目录
   - 统一模块命名规范为{模块名}.module.ts
   - 保留业务逻辑模块：auth, member, rbac, admin, settings, upload, notification

4. 代码质量提升
   - 更符合NestJS最佳实践
   - 项目结构更清晰
   - 删除所有空壳和重复代码
   - 打包测试通过

技术改进：
- 使用TypeScript枚举替代PHP风格的Dict类
- 优化导入路径和模块引用
- 清理无用的空壳目录和文件
