fix(backfill): flip hrrr_status :queued -> :complete when data already present

hrrr_placeholder_jobs previously returned [contact.id] for any
post-2014 contact with pos1, regardless of whether the HRRR
profiles were already in the DB. That meant BackfillEnqueueWorker
re-flagged the same ~22k contacts as :queued on every 30 min
cron tick forever — HrrrPointEnqueuer saw 0 missing points and
inserted nothing, but the status field never advanced.

Now the placeholder also returns [] when every path point has
an hrrr_profile row, so mark_hrrr_status!/3's empty-list branch
flips the contact to :complete directly. Genuinely-missing
contacts still flow through HrrrPointEnqueuer unchanged.
