Issue #20: 修复PM审核不通过的问题，补充缺失的核心功能

- ✅ 新增统一响应格式 R<T> 实体类
- ✅ 新增 BusinessException 业务异常类
- ✅ 新增 ErrorCode 错误码枚举
- ✅ 完善全局异常处理 GlobalExceptionHandler，修复返回4xx状态码
- ✅ 新增文件上传模块：MinIO集成 + FileService + FileController
- ✅ 新增验证码模块：图形验证码 + 短信验证码 + CaptchaService
- ✅ 新增IP地址解析服务：IpService + IpController
- ✅ 完善数据字典模块：DictData实体类 + DictDataService + DictDataController
- ✅ 新增通用查询条件：PageQuery + QueryCondition
- ✅ 新增单元测试：CaptchaService、IpService、DictDataService
- 🔧 修复DictTypeMapper注入风格不统一问题

本次修复了PM提出的所有❌和⚠️问题，包括：
- 核心实体类缺失（R.java、BusinessException.java）
- 文件上传功能缺失（FileService、MinioConfig等）
- 验证码模块缺失（图形验证码、短信验证码）
- IP地址解析缺失
- 字典模块不完整（DictData CRUD + 缓存）
- 通用查询条件缺失
- 补充了基础单元测试覆盖核心逻辑

File changes:
- 新增 19个文件，1000+行代码
- 修复了GlobalExceptionHandler返回码问题
