Remove DEFAULT_COMMUNITY_REGISTRY, resolve_community_image, and the
OPENSHELL_COMMUNITY_REGISTRY override. Bare --from values are no longer
expanded into the OpenShell Community registry; the CLI and TUI now pass
explicit OCI image references through to the gateway unchanged. The
openshell-core image module is reduced to default_sandbox_image().
BREAKING CHANGE: community sandbox shorthand names and OPENSHELL_COMMUNITY_REGISTRY
are no longer supported; pass a full OCI image reference to --from.
Part of #3116.
