IPv4
Sanitizer that accepts only valid IPv4 address strings.
Valid IPv4 values are returned unchanged. Invalid input, null, and valid addresses from the wrong family return an empty string, matching Phalcon's common sanitizer pattern where failed scalar sanitization collapses to an empty form value.
