feat(web): 新增 web.console_log 开关；data_dir 默认改为 srv/mesh_mqtt_go

- WebConfig 增加 console_log 字段，关闭后 gin 不再向控制台打印 HTTP 访问日志（保留 Recovery）
- 默认值 true；旧配置加载时自动补齐并写回
- defaultDataDirForGOOS 默认目录由 var/lib/mesh_mqtt_go 调整为 srv/mesh_mqtt_go，与 install.sh 中 DATA_DIR=/srv/${SERVICE_NAME} 保持一致
- install.sh 模板同步加入 console_log: true
