Transfer模块第三阶段开发完成 - 验证和异常处理

第三阶段：验证和异常处理开发
- 验证类：创建TransferOutValidation转出验证类，支持完整的转出数据验证
- 验证器：创建TransferAppValidator、BusinessIdValidator、AmountValidator三个核心验证器
- 异常处理：创建TransferException基类和专门的异常类

验证功能：
- TransferOutValidation：转出订单完整验证，包括用户权限、资金余额、安全验证
- TransferAppValidator：应用配置验证，检查应用状态和配置完整性
- BusinessIdValidator：业务ID验证，确保格式正确和唯一性
- AmountValidator：金额验证，支持精度控制和范围检查

异常处理：
- TransferException：异常基类，支持上下文信息和日志记录
- InsufficientBalanceException：余额不足异常，提供详细的余额信息
- ExternalApiException：外部API异常，包含请求响应详情和重试判断

技术特点：
- 遵循用户偏好的验证模式，使用addError方法处理错误
- 完善的数据验证和安全检查机制
- 支持批量验证和静态验证方法
- 异常类提供丰富的上下文信息和辅助方法
- 金额验证器支持高精度计算和格式化

下一阶段：队列任务和命令行工具开发
