Fix: Prevent Position Manager from closing runner after on-chain TP2

- Detect on-chain TP2 fills in size mismatch logic and set tp2Hit flag
- Position size thresholds: <30% = TP1, <10% = TP2 (prevents runner from being closed)
- Ensures runner (5-20%) trails properly instead of being market-closed immediately
