fix(notifications): show fallback icon instead of checkerboard for missing theme icons

Browse Source 
When Qt cannot resolve a notification icon name (e.g. "audio-headset" from
Blueman) because the icon theme is not properly configured, the
IconImageProvider returns a purple/black checkerboard missingPixmap.

Check icon existence via ThemeIcons.iconExists() before returning the
image:// URI, so NImageRounded displays its fallback icon instead.
