Fix backtest data source and chart view detection bugs

- Fix market/symbol key mismatch in PythonGenerator.py (6 locations)
  causing backtest to use wrong trading pair (BTC/USD vs BTC/USDT)
- Fix backtesting.py to always use default_source for backtest data
- Fix exchange/exchange_name key mismatch in app.py and BrighterTrades.py
  causing strategy dialog to show wrong current chart exchange
- Add favicon links to standalone HTML templates
- Add AI strategy dialog template
- Update tests and documentation
