What is the share of Al Kafi Net from the amount paid for the programming service, or is the entire amount given to the female friend who performed the work?

The café's share of the money depends on the agreement between you and your friend, the program designer. If you agreed with her to give her the full amount agreed upon with the client, then the café is not entitled to anything. If the agreement was for a specific amount, then she is only entitled to that amount, and anything in excess belongs to the café. If the agreement was for a percentage in exchange for mediation, then this is a permissible brokerage. If there was no agreement, then the lease is invalid, and she is entitled to a fair wage, and anything in excess belongs to the café.
