Fix timeframe selection bug and syntax errors

- Fixed critical timeframe mapping bug where '4h' was interpreted as '4 minutes'
- Now prioritizes minute values: '4h' -> ['240', '240m', '4h', '4H']
- Added fallback mechanism to enter exact minutes (240) in custom interval input
- Fixed multiple syntax errors in tradingview-automation.ts:
  * Missing closing parentheses in console.log statements
  * Missing parentheses in writeFile and JSON.parse calls
  * Fixed import statements for fs and path modules
  * Added missing utility methods (fileExists, markCaptchaDetected, etc.)
- Enhanced timeframe selection with comprehensive hour mappings (1h, 2h, 4h, 6h, 12h)
- Added detailed logging for debugging timeframe selection
- Application now builds successfully without syntax errors
- Interval selection should work correctly for all common timeframes

Key improvements:
✅ 4h chart selection now works correctly (240 minutes, not 4 minutes)
✅ All TypeScript compilation errors resolved
✅ Enhanced debugging output for timeframe mapping
✅ Robust fallback mechanisms for interval selection
✅ Docker integration and manual CAPTCHA handling maintained
