 🛠️ [TASK] : Migrate all images to ChainGuard

ChainGuard Images: https://www.chainguard.dev/chainguard-images

ChainGuard is a startup in the software supply security area that provides hardened images, free of CVEs, for multiple use cases. Adopting their images as our base images will immediately unlock security benefits by drastically reducing potential attack surfaces. It's also likely to reduce image sizes.
