fix(touch): show the joystick and skill buttons only in the game phase

The controls keyed off CPythonBackground's warp map name, which the
loading window sets before the game window exists, so the loading screen
already showed them. Also require CPythonNetworkStream's phase to be
"Game" (PORT_IsGamePhase, exposed as PythonBoot::InGamePhase).
