fix: Windows charmap crash + skip Python check in packaged builds

- Fixed fatal UnicodeEncodeError on Windows: banner box-drawing chars
  (U+2566 etc.) crash cp1252 console. Added sys.stdout UTF-8 reconfigure
  at import time + ASCII fallback banner on encode failure.
- Applied UTF-8 fix to logger.py so all log output is safe on Windows.
- Skip checkPythonDependency() when app.isPackaged — packaged builds use
  the self-contained wshawk-bridge binary, no system Python needed.
