Subject: [PATCH] Add complete volatility filters v1.12 (Anti-Chop)

- ATR filter: Blocks trades when volatility < 0.5% (narrow bands)
- ADX filter: Blocks trades when trend strength < 20
- CheckVolatilityFilter() called before every trade entry
- Prevents over-trading in choppy/consolidating markets
- Both filters ON by default, configurable via inputs
- Version bumped to 1.12
