Fix buy listing support: thread ListingType through processing pipeline

Browse source 
The listing processor was hardcoded to create RentListing objects and
query only the rentlisting table. Buy listings fetched from Rightmove
were stored in the wrong table with missing fields. This threads
ListingType through ListingProcessor and all Step subclasses so the
correct model (RentListing/BuyListing) is created, the correct table
is queried, and buy-specific fields (service_charge, lease_left) are
parsed from the API response and included in GeoJSON streaming output.
