fix(propagation): bound ScoreCache to 18-hour forecast window
Hot pods were restart-looping every ~25 minutes on liveness probe
timeouts. Root cause: ScoreCacheReconciler mirrored every .prop file
from NFS into ETS, including 7 days of GEFS Day 2-7 forecasts. With
23 bands × 43 valid_times × ~2 MB per grid = 1.95 GB in the
propagation_score_cache table alone; GC sweeps starved the
scheduler enough that /live dropped its 3 s budget.

The /map UI only ever requests the [now-1h, now+18h] window. Share
that bound as Propagation.hot_cache_window/0 and apply it in the
reconciler's disk-scan path plus NotifyListener's post-warm prune.
Long-horizon GEFS files stay on disk and are still served via the
lazy read_from_disk_and_cache path when requested directly.

Adds ScoreCache.prune_outside_window/2 (inclusive bounds) and
updates the reconciler tests to use relative-to-now timestamps
since hardcoded fixture dates now drift out of window.
