feat: cache and retrieve public IP address

This commit adds functionality to cache the public IP address for 24 hours. If the cached IP address is older than 24 hours or doesn't exist, a new request is made to retrieve the public IP address. The retrieved IP address is then stored in a file for future use. Additionally, if there are any errors during the retrieval process, appropriate warning messages are logged and default values are set for the IP address, country, and country code.
