chore: Add privacy policy for new users

This commit adds a privacy policy feature for new users. When a new user joins, the code reads the privacy policy from the "POLICY.md" file and sends it to the user in chunks of 4096 characters, respecting Telegram's character limit. This ensures that the privacy policy is sent in a readable format without splitting it in the middle of a line.
