fix(ebike): allow player input during mount/dismount camera transition

Add lockInput option (default true) to animateCameraTransformTransition
so ebike mount/dismount can keep player input active during the 1s
camera tween instead of locking via setCinematicPlaying.

Also drop the unused camPointPos/dropPointPos debug vars and the
matching debugRestingPosition state — the consuming JSX has been
commented out for a while.
