fix(qa): restore Google 3D before switching Street View off in gate cleanup

The Street View step's cleanup switched the Street View chip off after the
step had left Google 3D, where the chip is hidden by design. The click then
threw "failed to find element", replacing the step's real result (here, a
Google key refusal) with a selector error. Return to Google 3D first, then
switch the chips and restore the original map.
