fix(syslog-serve): 扩大微步5万条日志响应容量

- 按50000条、每条最大10KiB将响应上限调整为512MiB
- 将微步适配器最大响应字节数提高至536870912
- 将JSON解析token上限由200万提高至2500万
- 同步放宽管理接口和达梦数据库响应大小约束
- 更新微步任务模板、v6升级脚本和现场部署文档
- 增加50000条及512MiB配置边界测试
- 更新启动版本标识为WEIBU_5S_50000_512M_V20260917_71

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