- outbound.py: 出库审批5个端点全补@permission_required(outbound_list)
- purchase.py: 采购管理7个端点全补@permission_required(inbound_buy)
- borrow_service: 借库审批列表通过applicant_id关联用户表过滤公司
- outbound_service: 出库审批列表通过applicant_id关联用户表过滤公司
- purchase_service: 采购列表通过base_id+requester_id双路过滤公司
- base_service/search_material: 去除debug日志
