Add Bollinger Bands Volatility Protection indicator support

- Introduced BollingerBandsVolatilityProtection indicator in GeneticService with configuration settings for period and standard deviation (stdev).
- Updated ScenarioHelpers to handle creation and validation of the new indicator type.
- Enhanced CustomScenario, backtest, and scenario pages to include BollingerBandsVolatilityProtection in indicator lists and parameter mappings.
- Modified API and types to reflect the addition of the new indicator in relevant enums and mappings.
- Updated frontend components to support new parameters and visualization for Bollinger Bands.
