Fan with Remote issue

I think you have this reversed. The receiver controls the fan and light separately with inputs of white and black (neutral and hot, respectively) and outputs of white, blue and black (neutral, switched hot for light and switched hot for fan, respectively).

You could have only one wall switch provide input to the receiver and use the remote to control the fan and light independently. The other switch and its hot would be unused. If you mount the receiver on the wall switch, this might satisfy the requirement that there be a light switch on the wall. You could cover the unused switch with a shabbat light switch cover, e.g. these.  

If you want to forego having the light controlled by the remote, and just have the light controlled by the wall switch (to satisfy the code requirement), you could operate the fan with the remote, and have the line hot to the receiver be the switched hot from the fan wall switch. But the blue output from the receiver to the light would not be used. Instead you would connect the hot from the light wall switch directly to the blue wire to the light. You can do this because there is a common neutral white in the cable from the wall to the ceiling box.
