feat(syslog-serve): 优化微步5秒窗口与5万条日志采集

- 将 API 拉取任务的 lookbackSeconds 通用默认值调整为 0
- 微步任务采用5秒时间窗口、50000条单窗口上限和64MiB响应保护
- 将微步适配器及管理接口的 pageSize 上限放宽至50000
- 将 API 调度扫描默认周期调整为1000毫秒
- 兼容新旧调度扫描环境变量名称
- 更新达梦数据库 PAGE_SIZE 约束及 LOOKBACK_SECONDS 默认值
- 补充 v6 数据库预检、升级和验证脚本
- 更新微步任务模板、现场操作说明和启动版本标识
- 增加配置边界及启动参数自动化测试

验证：
- JDK 8 Maven测试通过：167个，失败0，错误0，跳过2
- git diff --check通过
