refactor(mobile-app): 重构账号创建流程，分离钱包获取逻辑 

API 变更:
- POST /user/auto-create 快速返回 userSerialNum, username, avatarSvg
- GET /user/{userSerialNum}/wallet 异步获取钱包和助记词

AccountService:
- 移除 MPC share 本地加密逻辑
- 新增 getWalletInfo() 方法支持轮询获取钱包状态
- CreateAccountResponse 移除 userId，使用 userSerialNum

页面修改:
- onboarding_page: 适配新的创建账号响应
- backup_mnemonic_page: 进入时调用 API 获取钱包，支持 loading/error 状态
- verify_mnemonic_page: 字段从 serialNumber 改为 userSerialNum
- wallet_created_page: 同上

清理:
- 删除 mpc_share_service.dart
- 删除相关测试文件
