Extract documents page layout into a tv variant

The results container hand-wrote its layout classes and toggled the
dimmed state with a string-interpolated conditional. Move both the page
shell and the busy/dimmed state into a documentsLayout tv variant, and
reuse it in the skeleton so the loading and loaded layouts share one
source of truth.
