Keep delete affordances neutral until the confirmation

Row delete buttons, overflow-menu delete items and per-row revoke
buttons painted red in lists, so a list of tokens or shares read as a
wall of alarms. They now sit in the muted tone (foreground on hover)
or as an outline button; the red is kept for the confirmation dialog
that every one of them opens, and for the danger zones, which are a
destructive card-wide action by design.
