critical: Fix ADX-based runner SL in on-chain fill detection path

The ADX-based runner SL logic was only applied in the direct price
check path (lines 1065-1086) but NOT in the on-chain fill detection
path (lines 590-650).

When TP1 fills via on-chain order (most common), the system was using
hard-coded breakeven SL instead of ADX-based positioning.

Bug Impact:
- ADX 20.0 trade got breakeven SL ($138.355) instead of -0.3% ($138.77)
- Runner has $0.42 less room to breathe than intended
- Weak trends protected correctly but moderate/strong trends not

Fix:
- Applied same ADX-based logic to on-chain fill detection
- Added detailed logging for each ADX tier
- Runner SL now correct regardless of TP1 trigger path

Current trade (cmi5zpx5s0000lo07ncba1kzh):
- Already hit TP1 via old code (breakeven SL active)
- New ADX-based SL will apply to NEXT trade
- Current position: SHORT $138.3550, runner at breakeven

Code paths with ADX logic:
1. Direct price check (lines 1050-1100) ✅
2. On-chain fill detection (lines 607-642) ✅ FIXED
