feat: Implement HTS (Higher Timeframe Trend System) strategy

- Add HTS strategy engine with crossover and alignment-based entries
- Implement Auto HTS feature (computes on TF/4 from 1m data)
- Add 1H Red Zone filter to validate long signals
- Add channel-based stop loss with RTL functionality
- Enhanced visualization with 30% opacity channel lines
- Fixed data alignment in simulation (uses htsData instead of mismatched indices)
- Fixed syntax errors in hts-engine.js (malformed template literals)
- Fixed duplicate code in simulation.js
- Added showSimulationMarkers to window object for global access
- Enhanced logging for trade signals and simulation results
- Fix missing prevFastHigh/currFastHigh in hts-visualizer.js
- Disable trend zone overlays to prevent chart clutter
- Implement client-side visualization for trade markers using line series
- MA strategy indicator configuration fixed (was empty during engine run)
- Made entry conditions more permissive for shorter timeframes
- Added comprehensive error handling and console logging
