fix(dashboard): fix ContributorStack each-block key and add accessible avatar labels

- Replace (actor.name ?? actor.initials + i) with (actor.initials + '-' + actor.color)
  to fix operator-precedence bug that made keys order-dependent when name is null
- Add role="img" + aria-label={actor.name ?? actor.initials} so screen readers
  and touch users can access contributor names
