feat(store): 新增 RechargeStore 充值订单数据访问层

实现充值订单的完整 CRUD 操作：
- Create: 创建充值订单
- GetByRechargeNo: 根据订单号查询（不存在返回 nil）
- GetByID: 根据 ID 查询
- List: 支持分页和多条件筛选（用户、钱包、状态、时间范围）
- UpdateStatus: 更新状态（支持乐观锁检查）
- UpdatePaymentInfo: 更新支付信息

测试覆盖率: 94.7%（7个方法全部覆盖）
- 包含正常流程、边界条件、错误处理测试
- 使用 testutils.NewTestTransaction 和 GetTestRedis
- 所有测试通过
