[fix](trx-frontend-http): force style recalc before reading bookmark theme colors

getComputedStyle may return stale CSS variable values if the browser
has not flushed the style recalculation after changing data-theme. Force
a recalc by reading a property value first. Also clear cached bookmark
DOM keys so the next draw pass rebuilds chips from scratch.
