Fix Bug #443: 手术计费：点击"签发"耗材时异常报错

**根因分析**：
前端 handleSave 签发时，仅从 contentJson 解析数据后发送，缺少 encounterId、patientId、locationId 等关键字段。这些字段在 API 响应顶层（不在 contentJson 中），导致后端签发时字段为空。

**修复方案**：
- 前端：在 handleSave 的 saveList 映射中补充 encounterId、patientId、locationId（对应 positionId）、adviceType 等顶层关键字段
- 后端：handDevice 中 locationId 为空时，优先查询已有 DeviceRequest 的 performLocation 作为回退，避免覆盖为默认科室
