Each root and policy row is one line: identity left, chips at the right
edge, then pencil/trash icon controls — the episode-row idiom instead of
a two-line group. Every icon action's aria-label names the action and
the row (edit root /mnt/media/tv/main). Delete keeps the arm-then-confirm
behaviour via the shared armedDeleteIcon; the local text-button
armedDelete is gone with it. Under 46rem the row wraps like an episode
row: identity, chips full-width, actions keeping the right edge.
