Subject: [PATCH] Add fallback handling for missing icon files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add graceful fallback behavior when icon image files (refresh.png, settings.png, MSMD32.png) are not found. The application now uses Unicode symbols (⟳, ⚙) as button text alternatives, preventing crashes when running without bundled assets.
