[PATCH 1/5] ui-shared: add viewport tag for baseline mobile usability

[Rito Rhymes]

Set the viewport so mobile browsers render at device width by default,
instead of using a desktop-width initial layout.

This is the first essential step in preventing the "panzoom dance" of
pinch-zooming and panning just to read content. This is the baseline
needed for mobile CSS fixes in follow-up commits.

It does not fully fix mobile layout issues on its own; follow-up CSS
patches address remaining overflow and scrolling issues.
