- AdminTaskWorker: remove scorer_diff no-op clause (propagation_scores table
was dropped pre-cutover; queue is drained).
- Weather: remove load_weather_grid_from_db/1 fallback — Rust writes
ProfilesFile for every forecast hour, so the DB path was unreachable
in practice and loaded stale pre-cutover data when it fired.
- Weather.build_grid_cache_row/4 now prefers persisted fields from the
ProfilesFile profile map (surface_refractivity, min_refractivity_gradient,
ducting_detected, duct_characteristics) over re-deriving from the raw
profile, matching the old DB-path semantics.
- NotifyListener: wrap per-band warm in try/rescue so one corrupt or
mid-rename .ntms file doesn't abort the remaining bands. Failures log
a warning with band + valid_time; successes still emit one info line.
- weather_grid_test: rewrite insert_hrrr_profile helper to write
ProfilesFile directly and drop the "only returns points on 0.125 grid"
test (filter was a property of the deleted DB fallback; Rust writes
only grid points by construction).
