critical: FIX adaptive leverage broken - smart entry used 1x instead of 10x (Bug #85)

SYMPTOM:
- Database shows leverage=10 for quality 95 signals
- Drift shows actual leverage 0.99x (essentially 1x)
- User expected ,960 position (10x), got 92 (1x)

ROOT CAUSE:
- Dec 14 fix (commit 5aad42f) passed wrong variable to smart entry queue
- Line 569: positionSizeUSD: positionSize (BASE size without leverage)
- Should be: positionSizeUSD: positionSizeUSD (LEVERAGED size)
- positionSizeUSD correctly calculated at line 504: positionSize * leverage

IMPACT:
- ALL smart entry timeout trades since Dec 14 used 1x leverage
- Adaptive leverage completely bypassed for queued signals
- User losing 90% of profit potential on quality 95+ signals

THE FIX:
- Changed line 569 from positionSize to positionSizeUSD
- Now passes correctly leveraged size to queue
- Smart entry timeouts will use adaptive 10x leverage

VERIFICATION:
- Container restarted: 2025-12-16 09:44:24 UTC
- Next smart entry timeout trade will show 10x leverage in Drift
