feat: autopilot book to 4 positions x 5x notional at 20x leverage

Was 2 positions x ~equity×1.2 — too few holdings and no room for shorts
(the 2 slots filled with the strongest signals, which were long-leaning, so
the balanced candidate pool never got expressed as short trades).

Now: max 4 positions, each sized at equity×5 notional, 20x leverage. Four
positions × 5x = 20x total account notional = full margin at 20x — the
operator's requested ceiling. This gives room for ~2 long + 2 short and
bigger single positions; the existing direction-balanced candidate selection
plus long/short coverage fills both sides when strong bearish signals exist.

Applied across all three config sources (default template, quick-create
preset, studio unified) with matching test assertions and 20x prompt copy.
