hailin 10b25e222e fix: 防止钱包生成中状态下重复触发MPC keygen
问题:
- 前端在钱包状态为"generating"时仍然调用retryWalletGeneration
- 后端identity-service没有检查生成中状态
- mpc-service没有幂等保护,可能导致同一用户多次keygen

修复:
1. 前端 wallet_status_provider.dart:
   - 只在"failed"状态下才触发重试
   - "generating"状态只更新UI,继续轮询等待

2. 后端 identity-service user-application.service.ts:
   - retryWalletGeneration添加Redis状态检查
   - pending/generating/deriving状态下跳过重试
   - 只有failed或无状态时才触发重试

3. 后端 mpc-service keygen-requested.handler.ts:
   - 使用分布式锁防止同一用户重复keygen
   - 锁TTL为5分钟,覆盖整个keygen过程
   - 无法获取锁时跳过请求
