hailin 9cac91b5f0 feat(blockchain): 将提现转账从私钥签名改为 MPC 签名 
背景:
- 原实现使用 HOT_WALLET_PRIVATE_KEY 进行热钱包签名
- 私钥直接存储存在安全风险
- 系统已有 MPC 基础设施，应该复用

改动内容:

1. 新增 MPC 签名客户端
   - infrastructure/mpc/mpc-signing.client.ts: 调用 mpc-service 的签名 API
   - 支持创建签名会话、轮询等待、获取签名结果

2. 重构 ERC20 转账服务
   - domain/services/erc20-transfer.service.ts: 从私钥签名改为 MPC 签名
   - 移除 Wallet 依赖，改用 Transaction 手动构建交易
   - 使用 MPC 签名后广播已签名交易

3. 新增初始化服务
   - mpc-transfer-initializer.service.ts: 启动时注入 MPC 客户端
   - 解决 Domain 层和 Infrastructure 层的循环依赖

4. 新增热钱包初始化脚本
   - scripts/init-hot-wallet.sh: 便捷创建系统热钱包的 MPC 密钥
   - 支持配置门限值、用户名等参数

5. 更新配置
   - 移除 HOT_WALLET_PRIVATE_KEY 依赖
   - 新增 MPC_SERVICE_URL, HOT_WALLET_USERNAME, HOT_WALLET_ADDRESS
   - 更新 docker-compose.yml 和 .env.example

部署前需要:
1. 运行 init-hot-wallet.sh 初始化热钱包
2. 配置 HOT_WALLET_USERNAME 和 HOT_WALLET_ADDRESS
3. 向热钱包充值 USDT 和原生币(gas)
