Fix TG WebApp: isAvailable только если есть initData

Browse Source 
Раньше isAvailable=true если window.Telegram.WebApp объект существовал
(SDK грузится всегда). Но методы кидали WebAppMethodUnsupported вне Telegram.

Теперь: isAvailable=true только если есть initData (мы внутри Telegram)
Все методы (close, sendData, haptic, showAlert, showConfirm) — early return если не внутри Telegram.
