Instead of fetching all zones and matching, iterate through domain parts and check each against the API until a valid zone is found. Same approach as GoDaddy DNS plugin. Example: _acme-challenge.test.example.com - Try: test.example.com → 404 - Try: example.com → 200 ✓ → zone found! Script reduced from 304 to 255 lines.
