fix: 修复多个服务的 Docker 健康检查和构建配置

identity-service:
- 修复 HEALTHCHECK URL: /health → /api/v1/health

wallet-service:
- 修复 HEALTHCHECK URL: /health → /api/v1/health

leaderboard-service:
- 修复端口: 3000 → 3007
- 添加 HEALTHCHECK (/api/health)
- 添加非 root 用户 (nestjs)
- 添加 NODE_ENV=production

mpc-service:
- builder 阶段从 alpine 改为 slim (解决 Prisma 兼容性)
- 添加 OpenSSL 依赖到 builder 阶段
- 添加 wget 依赖
- HEALTHCHECK 从 node 脚本改为 wget
