fix(backend): SupplyHierarchy change-requests systemId 改为可选 + ((Number)→Long.valueOf) 解析修复

- supply-hierarchy/change-requests 入口: 移除 'systemId 不能为空' 强校验, systemId 改为可选过滤
- Service.getChangeRequests: 仅在 systemId != null 时加入 where 条件
- 全 Controller 20 处 ((Number) ...).longValue() → Long.valueOf(... .toString()) 防 String/Integer 类型解析异常
