fix(theseus): Presearch is frozen in the engine catalog

Browse source 
presearch.com has redirected every request, searches included, into a
dead host since 2026-09-28, so a user who picked it gets Cloudflare's
origin error instead of results. Rather than deleting the entry, a catalog
engine can now carry a frozen reason: it stays listed in Settings, greyed,
with the reason as its tooltip and an Unavailable badge where the switch
was; it is never enabled, never in the picker, never accepted as the
default from any path, and a profile that had it as default falls back at
startup. Turning it off still works, and deleting the field brings the
engine back exactly as the user had it.
