URL is a required API parameter, maybe throw an exception here ?

Pull request overview
This PR hardens DNS provider configuration by adding pre-connection URL validation in DnsProviderManagerImpl so user-supplied DNS provider endpoints are checked (and normalized via trimming) before being persisted or handed to provider clients.
Changes:
- Add
validateDnsServerUrl()and invoke it inaddDnsServerand whenupdateDnsServerchanges the URL. - Normalize URLs by trimming before duplicate checks and persistence.
- Update and extend unit tests to cover trimming behavior and rejection of invalid URLs (e.g., loopback, missing scheme).

Description
DnsProviderManagerImpl.addDnsServer/updateDnsServer accepted a user-controlled URL and passed it straight to PowerDnsProvider/PowerDnsClient with zero host validation — no egress check at all, unlike the template/webhook paths.
Added validateDnsServerUrl(), called at the top of addDnsServer and whenever updateDnsServer changes the URL.
