Fix: Product details now auto-scroll into view when Buy is clicked

Problem: When clicking Buy button, product details message appeared at bottom
but Telegram didn't auto-scroll to show it, leaving users confused.

Solution: Use replyToMessageId parameter to thread product details as a reply
to the user's button click message. This:
- Creates visual thread connection
- Encourages Telegram to show the response prominently
- Makes conversation flow more natural

Also wrapped activity tracking in try-catch to prevent blocking.

Technical Changes:
- ProductCarouselService: Added replyToMessageId optional parameter
- SendPhotoAsync/SendTextMessageAsync: Use replyToMessageId with allowSendingWithoutReply
- HandleProductDetail: Pass message.MessageId to carousel service
