Load queue depths on landing so picker doesn't flash "No wait"

After returnToFreebuffLanding, the picker applied bare {status:'none'}
with no queueDepthByModel and nextDelayMs returns null for 'none', so
stale zeros showed until POST. Kick off a fire-and-forget GET in
landing mode that extracts just queueDepthByModel (ignoring status,
so a stale pre-DELETE row can't trip the takeover branch), and render
blank hints instead of "No wait" while the snapshot is missing.
