Release 5.3.29

What Changed

• Reply-to-photo in Telegram. The operator sees a preview of which photo the client replied to.
• File upload validation. For invalid file types in the widget, the client sees a clear message instead of a crash.
• Skill group transfer. Fixed transfer to skill group — conversations are correctly reassigned with the right topic.
• Client steps history. Client steps history displays consistently, without duplicates.
• Timer and sync in scenarios. Improved timer settings persistence and added sync button in the scenario builder.

How It Changed

Reply-to-photo and widget files

Before: When replying to a photo in Telegram, the operator might not see context; invalid file uploads in the widget could cause errors.
Now: The operator sees a reply-to-photo preview; the client gets clear messages for invalid file types.
Why it matters: Full dialog context in Telegram and safe file uploads in the widget.

Skill group and steps history

Before: Transfer to skill group might not update the topic; client steps history could jump or show duplicates.
Now: Transfer to skill group updates the topic correctly; steps history is stable.
Why it matters: Correct routing of conversations and stable client history UI.
