Persist weather grid for every forecast hour via ProfilesFile
Extend the f00 profile persistence to cover every forecast hour
(f00-f18) so /weather keeps working across pod restarts and shows
forecast-hour atmospheric data without a fresh database. Route the
Weather cold path (latest_grid_valid_time, load_weather_grid,
weather_point_detail) through ProfilesFile first, with the legacy
hrrr_profiles table as a last-resort historical fallback. Warm
GridCache from the latest profile on app start so /weather is hot
the moment a pod boots.
