[PictureLoader] Seed per-host allowances on demand and skip hosts in 429 backoff

The quota reset re-filled every host's remaining allowance to a full
MAX_REQUESTS_PER_SEC as soon as the queue had a request for it, so a server
that was just rate limited could be hammered again at full speed immediately
after (or even during) recovery.

Only seed a host's allowance the first time it is dispatched in the current
second, seeded from its reduced sustained quota, and skip hosts still inside
their 429 backoff window entirely, handing the entry back to its worker so it
can wait the backoff out or fall through to another source instead of parking
in the queue with no reply pending. Deferrals wait on the host that is
actually blocking the request (cached-redirect targets and the reply host of
a 429) rather than the current card URL's host.

Rebased onto network-requests/request-pacing, which absorbed the earlier
pacing and dispatch-guard commits, and reuses its updateTimerState idle-429
recovery plumbing.
