hailin aa74e2b2e2 feat(mpc-system): add signing parties configuration and delegate signing support
- Add signing-config API endpoints (POST/PUT/DELETE/GET) for configuring
  which parties should participate in signing operations
- Add SigningParties field to Account entity with database migration
- Modify CreateSigningSession to use configured parties if set,
  otherwise use all active parties (backward compatible)
- Add delegate party signing support: user provides encrypted share
  at sign time for delegate party to use
- Update protobuf definitions for DelegateUserShare in session events
- Add ShareTypeDelegate to support hybrid custody model

API endpoints:
- POST /accounts/:id/signing-config - Set signing parties (first time)
- PUT /accounts/:id/signing-config - Update signing parties
- DELETE /accounts/:id/signing-config - Clear config (use all parties)
- GET /accounts/:id/signing-config - Get current configuration

hailin c52b6aa980 refactor(mpc-system): replace K8s party discovery with Message Router-based discovery
- Add GetRegisteredParties gRPC method to Message Router for party discovery
- Create MessageRouterPartyDiscovery adapter in Session Coordinator
- Remove K8s dependency from Session Coordinator (works in any environment)
- Add party registration to server-party-api on startup
- Fix docker-compose.yml: add MESSAGE_ROUTER_ADDR to session-coordinator

This change implements a fully decentralized party discovery mechanism:
- Parties register themselves to Message Router on startup
- Session Coordinator queries Message Router for available parties
- Works in Docker Compose, K8s, or any deployment environment

hailin 747e4ae8ef refactor(mpc-system): migrate to party-driven architecture with PartyID-based routing
- Remove Address field from PartyEndpoint (parties connect to router themselves)
- Update K8s Discovery to only manage PartyID and Role labels
- Add Party registration and SessionEvent protobuf definitions
- Implement PartyRegistry and SessionEventBroadcaster domain logic
- Add RegisterParty and SubscribeSessionEvents gRPC handlers
- Prepare infrastructure for party-driven MPC coordination

This is the first phase of migrating from coordinator-driven to party-driven
architecture following international MPC system design patterns.

Developer 4db5534372 feat(mpc): 添加 server-party-api 服务,实现用户 share 生成
新增 mpc-system/services/server-party-api:
- 为 mpc-service 提供同步的 TSS keygen/signing API
- 参与 TSS 协议生成用户 share 并直接返回(不存储)
- 支持 API Key 认证
- 端口 8083 对外暴露

更新 mpc-service TSSWrapper:
- 改为调用 server-party-api 而非本地二进制
- 新增 MPC_SERVER_PARTY_API_URL 配置
- 超时时间调整为 10 分钟

架构: mpc-service -> account-service -> server-party-api -> TSS
