New tab: sort by recency, not by trust tier

Adam reported the latest design (a premium one) was showing up
about halfway down the New tab. The New-tab sort key was:

  (broken)  ||  (trust tier weight)  ||  (createdAt desc)

So a recent post from someone you don't follow ranked BELOW older
posts from people you do follow. That's the right behaviour for a
"Following" tab, not a "New" tab — users expect newest-first when
they click New.

Trust tier removed from the New-tab sort. Recency wins, with
broken-preview still as the only soft demotion so a wall of
missing images doesn't lead. The existing Trust dropdown on the
filter row is already there for users who want to scope to
follows / extended-follows; this change just stops it from being
silently the dominant sort.

Other tabs are unchanged: Popular still uses zap-total → reactions
→ trust → createdAt, Zapped uses zap-total → trust → createdAt,
Premium uses createdAt → unlock-min.
