network: Improve network interface handling and address resolution

- Return loopback address (127.0.0.1) when no network interface is selected
- Improve IPv4 address string conversion and handling
- Add explicit handling for "None" network interface selection
- Change IsAnyInternetRequestAccepted logging from ERROR to DEBUG
- Simplify internet request acceptance check to assume availability

This change makes the network interface handling more robust by providing
fallback behaviors and improving address resolution. It also reduces
unnecessary error logging for expected scenarios.
