Add no-cache option for force rebuild to bypass all Docker caching

- Add NO_CACHE output to cache strategy step
- Pass no-cache parameter to docker/build-push-action
- Ensures force_rebuild bypasses both GHA cache AND Docker layer cache
- Fixes issue where arm64 build was using cached layers even with force_rebuild=true
