feat(consignment): 支持多数量拆分与份额级赠送，并对齐待抢单看板

- 匹配引擎支持一条库存按剩余数量拆给多张整单/拼单，份额数量、报酬、分配数量按实际占用计算
- 「我的寄卖」改为按占用单/份额一行 + 剩余库存行，卖家按 allocation/share/workOrder 定位确认加好友与提交凭证
- 解绑/撤销/超时按 allocation 精确回补，修复单绑定字段在多占用下被误清的问题
- 拼单好友赠送改为份额级 friend_added_at / gift_available_at（迁移 146），新增后台按份额确认加好友入口与寄卖赠送列
- 待抢单匹配看板改用新引擎：覆盖全部寄卖分类、拼单余量、精确/非精确/冲突明细，去掉手枪品类写死
- 发布押金改为该提报单全部售出/作废后才释放，避免多件库存分多单时提前退款
- 补齐集成测试与单测：拆分、多占用、份额级独立冷却与凭证、看板新旧引擎对齐
