CMS Go module renamed from git.dev.alexdunmow.com/block/ninja to git.dev.alexdunmow.com/block/cms (along with the git remote rename on gitea). All import paths, string-literal rules, test fixtures, and doc references updated; (historical 'ninja-orchestrator' refs preserved). go mod tidy regenerated checksums.
