refactor(views): triggered-by back on the identity row, labeled toolbar facts

- The accountable human returns to the identity row next to the trigger
  mechanism (status · agent · trigger · person), where it's visible
  rather than buried in the ⓘ popover.
- Toolbar facts now carry explicit labels — "Created <time> · Took
  <duration> · N events" — instead of bare values the reader had to
  infer.
