🟡 Changes recommended

dnsResolve() still fails for direct IP (and IP:port) inputs because it attempts DNS resolution instead of returning the validated IP immediately.

Once you've addressed the issues Copilot identified, you can request another Copilot review.

Pull request overview

This PR updates Cleantalk\Common\Helper::dnsResolve() to accept and normalize more host input formats (string hostnames, URLs, and host:port), likely to support adding server IPs to whitelist/exclusion logic that relies on resolving HTTP_HOST.

Changes:

• Relaxed input validation from “must be a URL” to “must be a string”, with additional normalization steps.
• Added URL host extraction via parse_url() when a scheme is present.
• Added host:port stripping and broadened validation to accept either a hostname or an IP.
