fix: 修复仪表盘时区统计偏移、重复订阅、新增map_apple字段

- fix(order/model): QueryDateOrders/QueryDailyOrdersList 使用 time.Date 替代 Truncate 修复 UTC+8 时区偏移
- fix(user/model): QueryResisterUserTotalByDate 同样修复时区截断
- fix(traffic/model): QueryServerTrafficByDay 同样修复时区截断
- fix(activateOrder): 兜底查询防止过期用户重购产生重复订阅
- feat(api): SubscribeDiscount 新增 map_apple 字段
