huang 2570269c8d feat(wallet,tag): 钱包和标签系统多租户改造
核心变更:
- 钱包表:删除 user_id,添加 resource_type/resource_id(绑定资源而非用户)
- 标签表:添加 enterprise_id/shop_id(实现三级隔离:全局/企业/店铺)
- GORM Callback:自动数据权限过滤
- 迁移脚本:可重复执行,已验证回滚功能

钱包归属重构原因:
- 旧设计:钱包绑定用户账号,个人客户卡/设备转手后新用户无法使用余额
- 新设计:钱包绑定资源(卡/设备/店铺),余额随资源流转

标签三级隔离:
- 平台全局标签:所有用户可见
- 企业标签:仅该企业可见(企业内唯一)
- 店铺标签:该店铺及下级可见(店铺内唯一)

测试覆盖:
- 9 个单元测试验证标签多租户过滤(全部通过)
- 迁移和回滚功能测试通过(测试环境)
- OpenSpec 验证通过

变更 ID: fix-wallet-tag-multi-tenant
迁移版本: 000008
