Fix weekend gap risk and short signal detection

Grid EA (v3.1):
- Add weekend protection: close positions Friday before market close
- New settings: InpCloseBeforeWeekend, InpWeekendCloseHour, InpCancelPendingBeforeWeekend
- Prevents gap risk when market reopens Sunday/Monday
- FIX: Restore missing #include statements

Confluence EA (v1.14):
- Fix short signal detection by removing restrictive 'belowPivot' check
- Mirror BUY and SELL logic for symmetry
- Relax harmonic pattern tolerances (0.3-1.0 vs 0.5-0.8)
- Short signals now match buy signal generation

Add verify-short-signals.py to test short signal generation
