Recreate app icon and menu bar icon as SVG with proper resolution assets

- Rebuilt AppIcon as clean SVG (vector, infinitely scalable)
- Generated properly sized PNGs for all macOS icon slots (16-1024px)
- Updated Contents.json to reference correct per-resolution files
- Regenerated MenuBarIcon template images (black on transparent)
- Cleaned up unused MenuBarIcon.png / MenuBarIcon@2x.png
- SVG sources saved in Resources/ for future edits
