fix: improve listener configuration and error logging

- Add condition to skip port 53 attempts when using zero IP address
- Improve error logging by using structured error field instead of string formatting
- Remove redundant error information from log message format

The changes prevent unnecessary port 53 binding attempts when using zero IP
addresses and improve log readability by using zap's structured error fields.
