fix: Remove 5-candle time exit rule for v11.2 strategy

- Removed TIME_EXIT_5_CANDLE logic from position-manager.ts
- v11.2 backtest (+53.80%) didn't include this exit rule
- Trades will now be allowed to reach TP1 (+1.1%) instead of early exit
- Previous behavior: Exit after 25min if MFE < $30 (force-exited -0.20% trade)
- New behavior: Let trades run to configured TP1/SL levels

Rationale: The 5-candle rule was from an older Q>=95 strategy optimization.
v11.2 indicator already filters to PF 2.617 profitable setups, additional
time-based filtering was counter-productive and introduced untested behavior.
