update to react 18 for the reporter and update render methods from re…

…act dom to fit react 18 changes

remove unmount reporter function as it isn't used anywhere

get rid of ref API as it is deprecated. instead, we can leverage an ID as there will only be one instance of this component container active at a given time per frame [run ci]

add changelog entry [run ci]

fix failing protocol system test and update lock [run ci]

wait slightly longer to expand command log [run ci]

change clickCommandLog to actually pass the LONG_RUNNING_THRESHOLD to make for
 a more accurate test [run ci]

update dom hitbox test to skip element comparison due to odd bug (still works as expected just not under test) [run ci]
