Harden DB-reading pages with graceful fallback (no 500 without DB)

/news and six admin pages issued raw prisma reads with no try/catch, so
a DB outage rendered a 500 instead of an empty state. Wrap each read
(try/catch or .catch(() => fallback), preserving select() row types and
notFound() on the user-detail page). Matches the fail-soft pattern used
across the rest of the app.

Verified: tsc 0, next build 0, all public pages 200 against a dead DB.
