config: autopilot to 4x 5x notional at 20x leverage; short floor 0.75 -> 0.4

Two independent changes bundled:
- Position sizing back to 4 positions x 5x equity notional at 20x leverage
  (20x total account notional, ~5% liquidation cushion) — aggressive book
  size by operator choice, for bigger single positions on a small account.
- Forced short-coverage signal floor lowered 0.75 -> 0.4. At 0.75, a
  long-leaning board left every bearish candidate below the bar, so no short
  ever opened and the book became a one-directional long bet. 0.4 keeps
  genuine directional signals so the book actually hedges — which matters
  more, not less, at 20x.
