ci(docker): build multi-arch images (amd64 + arm64), bump Playwright base

Closes #5646

- Add QEMU setup and build linux/amd64,linux/arm64 in docker.yml so the
  Docker Hub image resolves to a multi-arch manifest
- Bump base image to mcr.microsoft.com/playwright:v1.61.0-noble (latest,
  ships arm64) to match the project's playwright dependency
