Terminal and graphics cards redrawn; rig slots 2 to 5 with electronics

Terminal: monitor with a top face and a trapezoid keyboard. Graphics card:
a metal bracket with ports, two fans, brand stripe, gold fingers with a PCIe
notch and power connectors on top, now 2x2 cells. Rig: two slots by default,
an upgrade slot that takes the next level's electronics (4 common, 1 rare,
2 rare) and consumes them at once; the card grid reshapes with the slot
count, which is kept on the rig's tags. Verified in game, including the
slot limit, the upgrade items, five cards, and save and reload.
