hailin ad4549e767 feat(co-managed): 支持 2-of-3 服务器参与签名功能 
修改内容:
1. participate_signing.go: 添加 ExecuteWithSessionInfo 方法
   - 新增方法供 server-party-co-managed 调用
   - 跳过 JoinSession 步骤（已在 session_created 阶段完成）
   - 将核心逻辑提取到 executeWithSessionInfo 共享方法

2. server-party-co-managed/main.go: 完整实现 co-sign 支持
   - 初始化 participateSigningUC
   - session_created: 移除签名会话拒绝逻辑，添加 2-of-3 安全检查
   - session_started: 根据 messageHash 判断 keygen/sign 并调用对应 use case

功能特性:
- ✅ 仅支持 2-of-3 配置的签名会话
- ✅ 100% 寄生 server-party 的 use_cases（与 co-keygen 架构一致）
- ✅ 不影响现有 server-party 功能
- ✅ 完整的两阶段事件处理（session_created + session_started）

安全限制:
- 仅当 threshold_t=2 且 threshold_n=3 时参与签名
- 其他配置（3-of-5, 4-of-7等）会被拒绝

测试:
- ✅ server-party-co-managed 编译成功

hailin 290b5ea766 fix(server-party-co-managed): use session_started event for participants list 
session_created event only contains initial co-managed parties,
but session_started event contains ALL participants including
external parties that joined dynamically via invite code.

hailin 2164664ca0 feat(server-party): add ExecuteWithSessionInfo for co-managed keygen 
Add new ExecuteWithSessionInfo method to ParticipateKeygenUseCase
for server-party-co-managed to skip duplicate JoinSession call.

- server-party-co-managed already calls JoinSession in session_created phase
- ExecuteWithSessionInfo accepts pre-obtained SessionInfo and skips internal JoinSession
- Refactor common execution logic to private executeWithSessionInfo method
- Update server-party-co-managed to use ExecuteWithSessionInfo on session_started

hailin fd6f84ce82 fix(server-party-co-managed): 修复死锁问题 - session_created 时立即 JoinSession 
问题：
- 原来在 session_created 时只存储 token，等待 session_started
- 但 session_started 需要所有 N 方都 JoinSession 后才触发
- 这导致死锁：co-managed-party 永远收不到 session_started

修复：
- Phase 1 (session_created): 立即调用 JoinSession + 存储 session 信息
- Phase 2 (session_started): 执行 TSS 协议（超时从此时开始计算）

hailin e114723ab0 feat(mpc-system): add server-party-co-managed for co_managed_keygen sessions 
- Create new server-party-co-managed service with two-phase event handling
  - Phase 1 (session_created): Store join token and wait
  - Phase 2 (session_started): Execute TSS protocol (same timing as service-party-app)
- Add PartyRoleCoManagedPersistent role to isolate from normal keygen/sign
- Update docker-compose.yml with 3 co-managed party instances
- Update deploy.sh service lists
- Modify selectPartiesByCompositionForCoManaged to use new role

This ensures co_managed_keygen sessions use dedicated parties that behave
100% compatible with service-party-app, without affecting existing keygen/sign flows.
