feat: add folder support and system tray icon

- Add "+ Ordner" button for recursive folder upload
- Drag & drop auto-detects folders and resolves files recursively
- Minimize to system tray instead of taskbar
- Tray icon with context menu (Öffnen/Beenden)
- Tray tooltip shows upload progress during active uploads
- Fix folder detection heuristic (size === 0, not % 4096)
- Fix concurrent drop guard to prevent double modal
- Fix duplicate "Erneut versuchen" context menu entry
- Add .catch() on async drop handlers
