fix(admin): align the Danger Zone with the shared card layout

The Danger Zone rendered a lone icon above a left-floating label with
the delete button dropped below, unlike every other admin section. Adopt
the shared SettingsCardHeader shape — icon, title, description, and the
destructive action in the status slot — so the structure matches the
rest of the console while the tint and warning icon keep it flagged as
destructive.
