Telegram may reinitialize window.Telegram.WebApp after app startup,
making cached references stale. Get a fresh reference inside
showPopupSafe to ensure the callback is registered on the current
WebApp instance.
Add popup guard in TelegramAdapter DialogController to prevent
"Popup is already opened" error. Migrate PromoOffersSection from
direct showPopup call to useDestructiveConfirm hook.
