rcv: Update RCV CSV typing and RCV Ventas preprocessing

[svillegas-cdd]

chore: Add TypeVar for RCV CSV parser typing

This was causing an issue en FD CL DATA that the functions were expecting a RcvDetalleEntry instead of a subclass

feat: Update "RCV Ventas" update preprocessing logic

• Implemented test for parse_rcv_venta_csv_file ensuring correct CSV parsing.
• Updated _RcvCsvRowSchemaBase.preprocess to handle empty and "-" values correctly.

This is to set as null the empty strings
