feat: 客户端接口数据模型基础准备

- 新增资产状态、订单来源、操作人类型、实名链接类型常量
- 8个模型新增字段（asset_status/generation/source/retail_price等）
- 数据库迁移000082：7张表15+字段，含存量retail_price回填
- BUG-1修复：代理零售价渠道隔离，cost_price分配锁定
- BUG-2修复：一次性佣金仅客户端订单触发
- BUG-4修复：充值回调Store操作纳入事务
- 新增资产手动停用接口（PATCH /iot-cards/:id/deactivate、/devices/:id/deactivate）
- Carrier管理新增实名链接配置
- 后台订单generation写时快照
- BatchUpdatePricing支持retail_price调价目标
- 清理全部H5旧接口和个人客户旧登录方法
