perf(header): poll sync status faster while work is in flight

Browse source 
The header polled every 30s, so the live "syncing" state (now gated on a real
running job) was usually missed between ticks. Poll every 8s while a job is
running or channels are pending, easing back to 30s once everything's settled,
via react-query's functional refetchInterval.
