Ensure the security of the web application by verifying the user

[CrazyTapok-bit]

To ensure the maximum security of the web application against data falsification and unauthorized access, I suggest adding user authentication. Especially since Telegram itself persistently offers to do this. What is mentioned in the documentation here.

To implement this functionality, I suggest connecting the TgWebValid library, it can cope with this very well, especially since it is added in almost a single line. By the way, I could help with this, and make some pull requests🙂
