bootstrap: search.younex.de Caddy host for the Meilisearch site search (VM 111)

Hand-written host next to panel.caddy so a golden-template refresh keeps it:
browsers reach only /multi-search, /indexes/*/search and /health; the admin
API is limited to the LAN and the cms.dotnews.media egress IP. Straight to
the VM, never through Varnish. Already live on VM 101 (2026-10-10).
