3.4 Implement user-defined indicator management system and enhance chart capabilities

Browse Source 
- Introduced a comprehensive user indicator management system in `components/charts/indicator_manager.py`, allowing users to create, edit, and manage custom indicators with JSON persistence.
- Added new default indicators in `components/charts/indicator_defaults.py` to provide users with immediate options for technical analysis.
- Enhanced the chart rendering capabilities by implementing the `create_chart_with_indicators` function in `components/charts/builder.py`, supporting both overlay and subplot indicators.
- Updated the main application layout in `app.py` to include a modal for adding and editing indicators, improving user interaction.
- Enhanced documentation to cover the new indicator system, including a quick guide for adding new indicators and detailed usage examples.
- Added unit tests to ensure the reliability and functionality of the new indicator management features.
