Address review: free-typing blend inputs, honest blend label, fix stale comment

- Simulator setup blend fields now keep a draft text buffer per field so an
  admin can clear/retype a weight without it snapping to 0/100; the committed
  futuresPct only re-syncs on a parseable number and normalizes on blur.
- futuresBlendLabel clamps a genuine blend to 1–99% so a near-extreme weight
  (e.g. 0.999) never reads as "0% Elo / 100% Futures"; the 0/1 extremes stay
  reserved for the "Elo only" / "overrides Elo" labels. Added test coverage.
- Refresh the stale comment in the simulate stub route, which referenced the
  removed intent="simulate".
