PR Summary

Low Risk
Low risk: changes are limited to input validation regexes for trust portal domains, broadening accepted values without altering verification or persistence logic.

Overview
Updates trust portal domain validation to support long TLDs by changing the domain regex from \.[A-Za-z]{2,6} to \.[A-Za-z]{2,63}.

This adjustment is applied consistently in the API DTO (GetDomainStatusDto) and in the app’s Zod schemas used by the custom-domain form and DNS check action, reducing false rejections for valid domains like .technology.
