fix: repair CI workflows and lockfile consistency

- Fix workflow step ordering: pnpm/action-setup must come before
  setup-node with cache: pnpm in all three test workflows
- Add rag-api/package-lock.json to the repo (was gitignored) so
  Docker npm ci has a lockfile to work with, matching rag-ui setup
- Remove package-lock.json from rag-api/.gitignore
- Update pnpm-lock.yaml and rag-api/package-lock.json after removing
  the unused turndown dependency
