Statement Browser: give sort dropdown a visible 'Sort by' label + reposition

The sort <select> was flex-wrapping to the second visual line under the
confidence slider, making it easy to miss. Now wrapped in the same
label-pattern as the confidence slider ('Sort by' label + dropdown) and
placed BEFORE the confidence slider so it sits adjacent to the other
filter controls on a normal viewport.
