PostgisDataRetriever now checks if the coord is a Station instance and uses the more efficient findCurrentDataForStation() query instead of the distance-based findCurrentDataForCoord(). Also removes the related commented-out code from PollutionDataFactory. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
PostgisDataRetrievernow dispatches tofindCurrentDataForStation()when the coord is a Station instancePollutionDataFactoryContext
Station detail pages passed a
Stationobject tofindCurrentDataForCoord(), which ran a distance-based query against thecurrent_datamaterialized view. The dedicatedfindCurrentDataForStation()queries thedatatable directly by station ID, which is simpler and more efficient.Test plan
