Adds published: boolean to the bootstrap wire contract. ConfigService
swaps to a new DEFAULT_BOOTSTRAP constant (all feature flags on, generic
branding/theme/pages) whenever the backend reports published: false, so
an unpublished marketplace renders a working demo instead of a blank or
broken page. Missing published field stays backward compatible (treated
as true). Documents the brand bootstrap wire shape for backend/ops use.
