host: seed nt-live-encore so the real import survives store wipes

host/blog-seed-nt-live-encore! imports the real post (its HTML-derived sx_content embedded)
via host/blog-import-post!, decomposing it into the :body composition of typed cards; wired
into serve.sh next to the demo seeds. Verified: after a full store wipe + reboot it reseeds
(HTTP 200, 4 images, 3 video embeds, tagged nt-live/films). Idempotent. blog 175/175.
