refactor: add mobile hero image to HomeAurora and adjust padding

- Added mobile-only hero image (/images/mobile/homepage.jpg) with mb-8 spacing and md:hidden visibility
- Changed vertical padding from py-16 to pb-12 pt-8 for mobile, maintaining lg:py-32 for desktop
- Positioned mobile image above content with w-full and object-cover styling
