    Send a draft email after user confirmation.
    
    This tool sends a previously created draft email. It should ONLY be used
    after explicit user confirmation to send the email.
    
    Prerequisites:
    - The user must be authenticated
    - You need a draft_id from send_email_reply()
    - You MUST have explicit user confirmation to send the email
    
    Args:
        draft_id (str): The ID of the draft to send.
        
    Returns:
        Dict[str, Any]: The result of the operation, including:
            - success: Whether the operation was successful
            - message: A message describing the result
            - email_id: The ID of the sent email (if successful)
            
    Example usage:
    1. Create a draft: send_email_reply(email_id="...", reply_text="...")
    2. Ask for user confirmation: "Would you like me to send this email?"
    3. ONLY after user confirms: confirm_send_email(draft_id="...")
    
    IMPORTANT: Never call this function without explicit user confirmation.
