Subject: [PATCH] =?UTF-8?q?fix(mpc-system):=20=E4=BF=AE=E5=A4=8D=E6=9C=8D?=
 =?UTF-8?q?=E5=8A=A1=20gRPC/HTTP=20=E7=AB=AF=E5=8F=A3=E5=86=B2=E7=AA=81?=

问题:
- session-coordinator 和 message-router 都默认使用 gRPC 50051
- 端口冲突导致 message-router 无法启动
- server-party 因无法连接 message-router 而失败

修复:
为每个服务分配独立的端口:
- account-service: HTTP 8080
- session-coordinator: gRPC 50051, HTTP 8081
- message-router: gRPC 50052, HTTP 8082
- server-party-1: HTTP 8083
- server-party-2: HTTP 8084
- server-party-3: HTTP 8085

服务器修复步骤:
  git pull
  sudo bash scripts/deploy.sh build   # 重新生成 systemd 服务文件
  sudo bash scripts/deploy.sh restart
  sudo bash scripts/deploy.sh status
