Feed rows wore punks and npubs because we asked for profiles one at a time.

A screenful of eighty rows sent eighty kind-0 REQs in the same breath.
Relays cap how many subscriptions a connection may have open, most were
refused, the five-second timeout expired, and the empty answer was then
believed for ten minutes — which is a real account dressed as a punk with
a shortened npub for the rest of the session. Measured against this
wallet's own feed, 131 of the 133 people on screen had a kind 0 sitting
on relays we were already connected to. It was never reach; it was us.

So profiles go out in batches: a 250ms beat collects a paint's worth of
rows into one request of up to 200 authors, and each batch paints as soon
as it lands rather than waiting behind the outbox fallback chasing
stragglers. A miss now backs off instead of sticking — fifteen seconds,
then half a minute, up to the ten minutes that's right for someone who
genuinely has no profile.

And noteRow no longer calls prefetchProfilePage. That fetches an author's
whole page — kind 0, relay list, last thirty notes — which for twenty rows
is sixty requests, and is what starved the batch in the first place. A row
is not a profile tap; the page still loads when the profile is opened.

profile-feed-test had rotted in three places (onboarding copy, and
.header-msgs now matching the settings button first) — repaired, not
rewritten.
