Add trading signal and execution layers with database integration

- Introduced `TradingSignalLayer` and `TradeExecutionLayer` for visualizing buy/sell signals and trade entries/exits on charts.
- Implemented signal validation and filtering mechanisms to ensure data integrity and user-configurable options.
- Enhanced market data layout to support new timeframes for improved user experience.
- Updated documentation to reflect the new signal layer architecture and its integration with the dashboard.
- Ensured compatibility with existing components while maintaining a modular structure for future enhancements.
