deploy: ship the search block, so the live web is on for this box

Owner's call. The code default stays off — no `search` block still means no
query leaves the LAN — but the deployed config now carries one, so a question
that is not about him reaches SearXNG before it reaches the ZIMs.

Nothing runs at http://searxng:8080 on homesrv yet. That is the designed
degradation and not a broken turn: an unreachable instance falls through to
Kiwix and she never says the search failed.
