feat(orders, subscriptions): implement banned user checks and improve remaining orders calculation

- Added `checkIsBanned` method calls in the `createOrder`, `getOrder`, `getOrders`, and `updateOrder` methods of the `OrdersService` to prevent actions from banned users.
- Updated the calculation of `remainingOrdersCount` in the `SubscriptionsService` to ensure it does not go below zero, enhancing subscription management accuracy.
