Implement comprehensive chart configuration and validation system - Introduced a modular chart configuration system in `components/charts/config/` to manage indicator definitions, default configurations, and strategy-specific setups. - Added new modules for error handling and validation, enhancing user guidance and error reporting capabilities. - Implemented detailed schema validation for indicators and strategies, ensuring robust configuration management. - Created example strategies and default configurations to facilitate user onboarding and usage. - Enhanced documentation to provide clear guidelines on the configuration system, validation rules, and usage examples. - Added unit tests for all new components to ensure functionality and reliability across the configuration system.
