Fix Bug #442: 手术计费：点击"删除"待签发耗材时异常报错，导致操作失败

根因：DoctorStationAdviceAppMapper.xml 中 getRequestBaseInfo SQL 的第二个 UNION 查询（手术计费耗材从 adm_charge_item 关联 wor_device_request）中，biz_request_flag 和 requester_id 使用了 CI.enterer_id（计费录入人），而非 DR.requester_id（设备申请创建人）。当录入人与当前操作人不一致时，biz_request_flag 为 '0'，导致删除操作被后端拒绝。

修复：将 CI.enterer_id 改为 COALESCE(DR.requester_id, CI.enterer_id)，优先使用 DeviceRequest 的 requester_id，确保 biz_request_flag 基于正确的创建人计算。
