重构: 将卡/设备的套餐系列绑定从分配ID改为系列ID

- 数据库: 重命名 series_allocation_id → series_id
- Model: IotCard 和 Device 字段重命名
- DTO: 所有请求/响应字段统一为 series_id
- Store: 方法重命名，新增 GetByShopAndSeries 查询
- Service: 业务逻辑优化，系列验证和权限验证分离
- 测试: 更新所有测试用例，新增 shop_series_allocation_store_test.go
- 文档: 更新 API 文档说明参数变更

BREAKING CHANGE: API 参数从 series_allocation_id 改为 series_id
