Subject: [PATCH] prerender nostr project pages with 24h cache

Community-only projects (no curated JSON) were missing from
generateStaticParams, so URLs like /hackathons/commerce/<id> 404'd in
production. Extend the project page + OG image generateStaticParams to
include every Nostr submission visible at build time, and bump the
shared submissions snapshot from cacheLife("hours") to ("days") so the
cached relay round-trip lasts 24h.
