/**
 * HIS 数据采集调度编排实现 ——
 * <b>由 {@code ruoyi-quartz} 的 {@code RyTask#dealHisData} + {@code collectSegmentData} 原样搬入</b>。
 *
 * <h3>搬运纪律（本类刻意"零改动"）</h3>
 * <ul>
 *   <li>站点分支（{@code xh} / {@code hn} / {@code sltd}-{@code nhfy}）、时间窗口算法、
 *       30 天分段回溯的段长与顺序、每个采集动作的先后、异常吞掉的范围、日志文案
 *       —— 全部与搬运前一致；</li>
 *   <li>唯一的形式变化：内部 VO（{@code ServiceSLTDInhospReqVO} / {@code ServiceSLTDDeptReqVO} /
 *       {@code HnDataGatherVO}）换成契约 DTO {@link SltdGatherReq} / 两个 {@code Date}，
 *       由 smartor 侧 Bridge 逐字段搬回原 VO；字段设置顺序与"显式置 null"都保留；
 *   <li>{@code CollectionUtils.isNotEmpty(...)} 换成等价的 {@code list != null && !list.isEmpty()}
 *       （避免为一次判空给模块引 commons-collections4）；</li>
 *   <li>{@code sys_config} 的读法<b>刻意保持</b> {@code selectConfigList(条件)} + 取第 0 行
 *       （含原实现的 LIKE 匹配与"不排序取首行"语义），没有改成 {@code selectConfigByKey}
 *       —— 那是"顺手优化"，会改变查询语义，回归时无法逐条比对。</li>
 * </ul>
 *
 * <h3>它不管什么</h3>
 * 真正的采集动作（HTTP 取数、入库）不在本类：那里仍在 smartor，经
 * {@link HisGatherApi} 契约调用，后续分批搬进本模块。
