fix(listings): extract PostGIS coordinates in read queries instead of returning 0,0

findByIdWithProperty and searchListings used Prisma include which cannot
extract PostGIS geometry(Point,4326) columns. Added raw SQL with ST_Y/ST_X
to return actual lat/lng. Search uses batch extraction via ANY() for efficiency.
