Resolve Himalayas apply URLs at fetch time to bypass Cloudflare

Himalayas jobs stored as himalayas.app/... URLs trigger Cloudflare when
Playwright navigates to them. Follow the redirect chain at fetch time with
a HEAD request so the actual ATS URL (Greenhouse, Lever, etc.) is stored
in the DB instead. No impact for already-external URLs.
