Trade only on loaded history; catch early TopstepX fills; fix SI/M2K point values

- Both clients track which accounts this process has loaded history for
  (historyReady). An account restarted, rebuilt, wiped or newly listed is
  ineligible until its fetch lands, instead of trading as a fresh stage-1
  first day; a failed fetch with no cache no longer reads as empty history.
  Waiting accounts get a targeted fetch on the next sync.
- Tradovate holds an account whose start-of-day balance moves without a fill
  (a payout between hourly Cash History runs) until a Cash History books it,
  so a payout-pending account isn't re-traded on its ended cycle.
- Wipe routes forget history through the client and count accounts whose
  history didn't come back as failures.
- TopstepX sendOrder picks up a fill that arrived before the place response,
  and its REST backstop uses the documented Trade/search and Order/search.
- POINT_VALUES: SI 5000 (was 50), M2K 5 (was 10).
