Pull Request Overview

This PR adds extraction of the Unix timestamp from incoming WhatsApp messages and implements a condition to check the age of the message (i.e., ignore messages older than 24 hours).

• Extracts and stores message_unix_time in the WhatsAppPresenter constructor and related methods
• Updates the tuple returned by extract_relevant_whatsapp_message_details to include the new timestamp
• Integrates a new is_message_too_old method in both the presenter and main webhook for early message rejection

• The condition is comparing the value of incoming_msg['type'] to the keys of incoming_msg, which is a logical error. Instead, check for the key's existence (e.g. 'if "type" in incoming_msg') or use a more appropriate validation logic.

incoming_msg_type = incoming_msg["type"] if incoming_msg["type"] in incoming_msg.keys() else "errors"
