fix(admin): neutralise the danger-zone card surface

Render the danger-zone section on the shared SettingsCard surface
(bg-card + border-border) instead of the destructive-tinted card edge.
A red card surface reads as alarming rather than premium; the danger
signal now lives only in the destructive delete button and its typed
confirmation dialog, with the AlertTriangle header icon still flagging
intent.
