Payment pages (folk-payment-page, folk-payment-request, folk-group-buy-page)
had zero or minimal media queries — now stack headers, reduce padding, and
resize iframes for 375px viewports. Other rApp dashboards (rchoices, rwallet,
rnotes, rfiles, rinbox, rforum, rtasks, rvote) gain consistent 768px/480px
breakpoints: collapsing grids to 1-column, shrinking fonts and padding, and
stacking flex rows on mobile. Also adds folk-payments-dashboard to the flex
centering rule in cart.css.
