fix(lottery): 增加广播任务时效保护并强化命令异常处理

- 为多个广播事件添加 retryUntil 方法，设置派发后 30 秒内必须执行，否则丢弃
- 修改 LotteryDrawTickCommand handle，添加异常捕获及错误日志，保证失败时返回 FAILURE
- 修改 LotteryHallCountdownCommand handle，添加异常捕获及错误日志，超时情况写入警告日志
- 针对 SettlementOrchestrator 和 DrawHallSnapshotBuilder 查询结果添加限制，防止数据量过大
- 调整计划任务 withoutOverlapping 调用，增加 expiresAt 参数避免任务锁死
- 更新 .env.example，完善本地开发与生产环境部署说明及日志配置说明
- 移除 e2e 相关测试代码、配置及依赖，精简项目体积
