feat: Enable multi-platform Docker builds and dynamic image tagging

Browse Source 
- Detect host architecture to set build platform - Support
multi-platform builds when MULTI_PLATFORM=1 or CONTAINER_REGISTRY is set
- Dynamically set image tag based on registry and platform - Pull pushed
images for local validation - Update all docker run and inspect commands
to use dynamic image tag
