Fix action drift during freeze states by parking ship and combat bodies

The level-up marquee, jump clip, and ack comm freezes gate world
drivers but not physics: the Arcade world still steps, so coasting
bodies kept gliding through the beat. Add _parkForFreeze() to zero
ship velocity/acceleration and all enemy/ally body motion every
frozen frame, killing any mid-freeze injection on the next tick.
