Resolve lat/lon to NWS gridpoint and associated URLs

Step 1 of the NWS forecast flow. Convert a lat/lon into the NWS gridpoint tuple (wfo, grid_x, grid_y) together with the URLs for the 7-day forecast, the hourly forecast, the raw forecast grid, the observation station list, and the forecast / county / fire weather zones. Sugra's own /forecast and /forecast/hourly endpoints chain this lookup internally; /point is exposed so clients that want to compose requests against the raw upstream URLs can do so without re-implementing the resolution. US only: lat/lon outside US territory returns 503. Cached 24 hours (a point-to-gridpoint assignment is stable for any given coordinate). Attribution: NOAA National Weather Service (api.weather.gov).
