docs(commons): add annotated mockup for the poll results page

Self-contained HTML mockup accompanying the poll results proposal: the
Android screen with seven numbered callouts, the Desktop deck column, the
loading / closed / empty states, and a side-by-side of the two candidate
readings for a multiple-choice percentage.

Mockup interiors use the app's real theme values from ui/theme/Color.kt
and Theme.kt so the screens read as Amethyst rather than as generic UI;
the annotation layer around them uses a separate neutral set. Light and
dark both supported, following the viewer's preference.
