Address review: choice copy, objector count, reopening states, touch

- A prompt without a selected option reads "Needs a choice", not
  "Ready to settle".
- The objection count is distinct people opposing the shown option or the
  whole decision.
- A rejected reopening candidate gets no line; once the card is reopened
  after the suggestion, the line reads "Reopened".
- "· Open card", the objection count and "· Suggested in Chat" stay
  unbroken; Open card uses brand ink and grows a 44px touch target on
  coarse pointers.
