доделай все чтобы все работало и чтобы при Регистрации в окне было две плашки ресепшионист и администратор
если пользователь хочет зарегистрироваться как один из них он должен написать все свои данные чтобы заполнить все поля в таблице
различие в том что если пользователь хочет зарегистрироваться в качестве администратора то ему при регистрации нужно обязательно ввести уникальный код

для входа в обоих случаях нужны просто логин и пароль после входа должно автоматически определяться какая роль у пользователя админ или ресепшионист
также при регистрации нужно писать все данные которые необходимы в базе данных


напиши полные коды для компонентов которые ты хочешь изменить
