Enhance Raspberry Pi OS image handling and dashboard UI

Browse Source 
Update the API to support streaming and decompressing of golden images in .img.xz and .img.gz formats on the fly. Modify the cloud-init build process to compress images to .img.xz for size reduction. Revise the dashboard templates to set 'desktop' as the default variant for Raspberry Pi OS builds, improving user experience and clarity in options. Update related scripts to ensure compatibility with the new image handling features.
