3.4 - 3.0 Strategy Configuration System

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.
