.hl-master carried margin-right:auto to push the buttons right when the
toolbar held a single control; with four it flex-shrank each one and the
captions wrapped one character per line. Group the toolbar into a controls
cluster and a right-aligned actions cluster (margin-left:auto so the buttons
stay on the right edge on the line they wrap onto), let .hl-master never
shrink or wrap, box the per-host profile section in its own bordered card
with a left-aligned hint, and drop the fixed 56px editor label width that
broke "包含的规则" onto two lines.
