Cut propagation_scores write cost with DELETE+COPY, skip-factors, UNLOGGED 
The scoring+upsert phase was ~4m40s per forecast hour and dominated
wall time. Three stacked optimizations attack it from different
angles.

replace_scores/2 is a new hot-path writer that does DELETE WHERE
valid_time = $1 followed by a plain insert_all (no ON CONFLICT
resolution). The chain worker rewrites the full (valid_time, all
bands) slice every forecast hour, so conflict detection was pure
waste. AsosAdjustmentWorker still uses upsert_scores because it
only rewrites the subset of cells near a station.

factors is now nullable. Forecast hours f01-f18 pass factors: nil
so the JSONB encode + toast write is skipped entirely — roughly
halves the data volume per run. point_detail/4 coalesces nil to
an empty map so the JS popup renders without a TypeError, and
scorer_diff only pulls the most recent valid_time that still has
factors (the f00 row).

propagation_scores is now UNLOGGED, so inserts bypass WAL entirely.
Durability tradeoff: an unclean shutdown truncates the table, but
PropagationGridWorker rebuilds it from HRRR every 3h so a lost
table is re-populated within one cron cycle.

Also adds docs/plans/2026-04-14-duckdb-scores-storage.md — a
speculative plan for a flat-file / DuckDB rewrite with explicit
trigger conditions for when to pick it up (partitioning deferred
too; revisit only if these three don't solve it).
