fix(layers): use KiCad 9 API for add_layer

Browse Source 
board.GetLayerStack() was removed in KiCad 9. Call SetLayerName and
SetLayerType directly on the board instead, and grow the copper layer
count via SetCopperLayerCount when adding inner layers. Without this,
add_layer raises AttributeError on any KiCad 9 installation.
