修复问题：
- 之前手机号注册只创建账户，不生成钱包
- autoCreateAccount 方法会触发钱包生成，但 register 方法没有

解决方案：
- 在 register() 方法中添加 MpcKeygenRequestedEvent 发布
- 与 autoCreateAccount() 保持一致的钱包生成流程

流程：
1. 验证短信验证码和推荐码
2. 创建用户账户并保存到数据库
3. 发布 UserAccountCreatedEvent（推荐关系等）
4. 发布 MpcKeygenRequestedEvent（触发异步钱包生成）
5. 返回 JWT Token 给用户

钱包生成异步流程：
- MPC Service 监听 MpcKeygenRequestedEvent
- 生成 MPC 密钥对，发布 KeygenCompleted
- Blockchain Service 派生区块链地址
- Identity Service 保存钱包地址到数据库
