fix(marketing): release and spotlight drafts carry their source project

draft_release_post / draft_release_video accept a project_id and the
release-proposal approve hooks pass the proposal task's own project;
the spotlight companion video forwards the spotlight draft's project
into open_video_task — previously it always authored against the
deployment-anchor project's motion/ tree regardless of which project
the spotlight was about. Omitted project_id keeps the anchor-project
fallback, so single-project deployments are unchanged.
