ui: stop the offline strip reserving a 48dp touch target

The clickable Surface enforced Material's minimum interactive size, so
trimming its row only moved the text inside a band that stayed 48dp
tall and kept the gap to the tabs. Make the strip itself clickable
instead, so it sizes from its padding, and pin it at 36dp.
