fix(unitree_g1): unfreeze exo joysticks in onboard teleop client

Without the robot->teleop feedback the normal loop provides, the RemoteController's
wireless_active gate latched True after the first non-zero exo axis, skipping
set_from_exo forever and freezing the sticks. Reset the latched axes each frame.
