Add layer option to move_component to support flipping components

Adds an optional `layer` parameter (e.g., 'F.Cu', 'B.Cu') to the
move_component tool. When specified, the component is flipped to
the target layer if it's not already on it. The response now also
includes the component's layer after the move.
