feat(build): enhance DMG maker configuration with custom layout

Add improved DMG installer configuration including custom name, window
sizing, and drag-to-Applications layout. Remove deprecated manual
codesign script from package.json as it's no longer needed.

- Configure DMG with branded name "ILR File Creator"
- Set custom window dimensions (660x400) for installer
- Add file and Applications folder positioning for better UX
- Include commented asset paths for future background/icon customization
- Remove manual codesign script (handled by forge)
