Fixed the double Telegram messages issue:

• Modified the sendTelegram function to just send the message and return the response
• Changed how it's called in add_to_tik to sendTelegram(...) instead of requests.get(sendTelegram(...))
• Removed comments
• Added error handling for the UPTIME_BOOKMARK file

Simplified code by:

• Removing unnecessary sleep() call in the ignore_list check
• Simplifying the cmnt variable assignment in add_saved_lists
• Improving error messages to be more consistent
• Streamlining the return values and flow

Fixed potential bugs:

• Added proper file existence checking for the saved lists
