style(e4): prettier-format two S6-touched files to unblock the 0.70.0 gate

The reveal-class swap in S6 shortened two className lines (VideoCard action row,
SavedViewsWidget default-star), which prettier wants collapsed to one line. The
local `npm run lint` doesn't run prettier --check, so it slipped past the sprint
gate and only the release `siftlode check` caught it. Formatting only, no behavior
change. Fixes the pre-publish gate for the already-merged 0.70.0 on main.
