shopfloor dashboard: Verdana font + full left-edge type-color bar

Switch the dashboard to Verdana (system font on the Windows kiosks - built for
on-screen distance reading, zero bundle) and drop the Archivo package. Restyle
the event card's type-color indicator to span the whole left edge of the card
(old-site style) instead of a small pill.
