feat(borrow,outbound): 默认免审批改造——命中物料需审批才走原流程

- models/base.py 加 is_approval_required 列及 isApprovalRequired 序列化；field_permissions 登记
- 新增 POST /inbound/base/batch-approval（批量设需审批，仿批量质检）
- borrow_service.submit_approval / outbound_service.create_request：明细含需审批物料→须选审批人走原审批；否则创建即 status=1(待库管执行)、不发审批邮件
- 判定按 (name,spec_model) 反查启用物料
