feat: 优化100人并发投票支持 + 修复奖项名称硬编码问题

服务端优化:
- Socket.IO 配置优化，支持高并发 WebSocket 连接
- 添加 connectTimeout、perMessageDeflate 等参数

压测脚本:
- 新增 vote-real-scenario.yaml 真实场景压测配置
- 支持 100人瞬间爆发、每人7票、不同投票速度模拟
- 添加随机延迟函数模拟真实用户行为
- 强制 WebSocket 传输避免 HTTP 连接限制

前端修复:
- 修复 PostcardItem、PostcardDisplay 奖项名称硬编码问题
- 组件现在从后端 awards 配置动态获取奖项名称
- 修复 LiveVotingView、AdminControl 传递 awards 数据
- 新增 gala 压测命令到 package.json

测试验证:
- 100人并发压测通过，成功率 100%
- P95 延迟 0.7ms，远低于 500ms 阈值
- 系统可稳定支持 3.3 倍现场负载
