huang e78f5794b9 feat: 实现客户端换货系统(client-exchange-system)
新增完整换货生命周期管理:后台发起 → 客户端填收货信息 → 后台发货 → 确认完成(含可选全量迁移) → 旧资产转新再销售

后台接口(7个):
- POST /api/admin/exchanges(发起换货)
- GET /api/admin/exchanges(换货列表)
- GET /api/admin/exchanges/:id(换货详情)
- POST /api/admin/exchanges/:id/ship(发货)
- POST /api/admin/exchanges/:id/complete(确认完成+可选迁移)
- POST /api/admin/exchanges/:id/cancel(取消)
- POST /api/admin/exchanges/:id/renew(旧资产转新)

客户端接口(2个):
- GET /api/c/v1/exchange/pending(查询换货通知)
- POST /api/c/v1/exchange/:id/shipping-info(填写收货信息)

核心能力:
- ExchangeOrder 模型与状态机(1待填写→2待发货→3已发货→4已完成,1/2可取消→5)
- 全量迁移事务(11张表:钱包、套餐、标签、客户绑定等)
- 旧资产转新(generation+1、状态重置、新钱包、历史隔离)
- 旧 CardReplacementRecord 表改名为 legacy,is_replaced 过滤改为查新表
- 数据库迁移:000085 新建 tb_exchange_order,000086 旧表改名
