Rig: base power draw follows the installed cards

The game recomputes a machine's draw from its base-draw tag whenever a
module is added or removed. The rig kept that tag at the body's 2 kJ, so the
game briefly rewrote the draw to a percentage of 2 kJ before the mod put it
back. The tag now carries the body plus all cards (without modules).
