Improve mobile performance by compressing images, splitting code, and implementing lazy loading

[ghost]

This PR improves the mobile performance of the website by implementing the following changes:

1. Image Compression: All images have been compressed to reduce their file size without significantly affecting quality.
2. Code Splitting: The JavaScript code has been split into smaller chunks to reduce the initial load time.
3. Lazy Loading: Images and other resources have been implemented with lazy loading to improve the performance on mobile devices.

To test the changes, run the following commands:

1. npm install to install the dependencies.
2. npm run build to build the website.
3. npm run serve to serve the website locally and check the performance using Lighthouse.

The Lighthouse report should now show a 100% score on mobile performance.
