PR Summary

Low Risk
Dependency-only CI action bump with no application or workflow logic changes; v3.12.0 mainly deprecates an install input this repo does not use.

Overview
Bumps docker/setup-buildx-action from v3.11.1 to v3.12.0 everywhere CI sets up Buildx, pinning the new commit SHA in the comment.

The version change is applied in composite actions docker-build-push, docker-ecr-login, and load-docker-images, and in deploy.yml for the stage and manifest jobs (alongside existing ECR/GHCR login steps). No workflow inputs or step configuration change—only the action reference.
