route the win-path restart through ResetCommand

The Restart button on the Win dialog called Simulation::reset() directly,
while the escape-menu and Game Over restarts enqueue a ResetCommand. That
bypassed the command chokepoint every sim mutation is supposed to flow
through (docs/replay_design.md), so a post-win restart was never recorded
into the replay stream, and it had UI code calling a sim mutator directly.

Mirror the Game Over path instead. The manual resetForNewGame() call goes
away with it: GameWorldView::onFrame already resets the view when it drains
a Reset command.
