Consistency — the Resolution order and Preferred-source order lists now use the exact
same .hybrid-source-item markup/CSS (card + arrows + priority number + pill toggle) as
the Download Source hybrid list, instead of the bespoke .vq-row styling. Resolution
keeps its enable toggle; source is order-only (no toggle), no brand icon (they're not
branded sources). Removed the now-dead .vq-row/.vq-arrow/.vq-toggle/.vq-rows CSS.
Pure UI; data-vq-* hooks preserved so the existing delegation/handlers are unchanged.
