Backfill Park Locations

Add a script to backfill missing location data for already-approved parks from their submission data, and make it executable from the admin settings interface. Implement a backfill function (SQL migration) and an edge function to trigger it, plus UI integration in Admin Settings to initiate the process. Ensure only parks with approved submissions and location data are linked to new location records, and expose results in admin.
