ci: publish multi-arch container image to GHCR

Build linux/amd64 + linux/arm64 from the existing Dockerfile on every push
to main, on git tags v*.*.*, and on manual workflow_dispatch. Pushes to
ghcr.io/metalfinger/refboard with tags :latest (default branch), :sha-XXX
(every push), and semver tags on releases. Uses GHA cache for speed.

Tightens .dockerignore so multi-arch builds don't ship docs/, examples/,
scripts/, .github/, or .docker-data into the image context.
