Place limit entries as soon as a demo plan is adopted (plan 3.2)

- The model gives a zone and a limit price inside it (below the mark for
  longs, above for shorts); the executor places the GTC limit order with
  the reduce-only stop right away instead of waiting for a 5m
  confirmation and entering at market, so entries pay maker fees
- Stop beyond the far edge of the zone by 0.5 x ATR14(5m), computed with
  the quantity at submission and rejected above 1%
- Unfilled limits are cancelled at expiry; a rejected entry cancels the
  plan instead of being retried every round
