fix(weather): reconcile_hrrr_statuses also flips OCONUS path points to :unavailable

Root cause of the "81,980 / 81,994" display that wouldn't advance:
14 contacts had pos1 inside the HRRR CONUS grid but pos2 or the
great-circle midpoint landed outside it (50°N+ into Canada, mid-
Atlantic, Pacific, Caribbean, Alaska). The Rust hrrr-point-worker
silently returns no profile for OCONUS points, so
`hrrr_data_fully_present?/1` never evaluated true and the contact
sat `:queued` forever.

The existing ContactWeatherEnqueueWorker.mark_hrrr_status!/3 already
flips to `:unavailable` on empty job lists via NarrClient.in_coverage?
+ Grid.contains?(pos1), but those checks only considered pos1 — not
the full contact_path_points list. When pos1 was in-grid but a
downstream point was not, the contact entered `:queued` and the
reconciler couldn't rescue it.

`reconcile_hrrr_statuses/0` now sweeps `:queued` contacts into two
buckets:
- ANY path point OCONUS → `:unavailable` (matches what the enqueuer
  would emit had it known about the downstream points);
- else, all points present → `:complete`.

Applied once in prod to 14 stuck contacts; cron path picks up any
new occurrences going forward.
