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.
