NEON-29: Idle gravity + snap when airborne (ledge / step drop)

_physics_idle_tick zeroed velocity with no gravity, so after walking off a
terrace or arriving slightly above the floor FLOOR_SNAP_IDLE could not reach
the ground and the body hovered until a new walk goal. Apply get_gravity()*delta
and FLOOR_SNAP_MOVING while !is_on_floor(). Budgeted idle branch now runs the
same physics when airborne instead of returning without move_and_slide.
