feat(spoof): пер-аккаунтный спуф с тумблером и прокидыванием в веб-аппы

- спуф теперь свой на каждый аккаунт, вмораживается при входе
- тумблер вкл/выкл в настройках (по умолчанию выключен)
- новый аккаунт добавляется со своим включённым спуфом (другое устройство)
- UA спуфа прокинут в Сферум, Цифровой ID (вебвью + HTTP)
- генерация выбирает Android или iOS; iOS отдаёт deviceType IOS
- экран спуфа показывает текущую личность, а не свежесгенерированную
