chore(ci): remove preview-build/preview-cleanup; inline docs-preview-cleanup-local

- Delete preview-build.yml (reusable workflow removed from this repo).
- Replace preview-cleanup.yml with docs-preview-cleanup-local.yml content:
  inline GitHub deployment + S3 cleanup via aws-auth (no docs-actions).
- Drop docs-actions reusable call from docs-preview-cleanup-local.
- Adjust docs-preview-local.yml header comment.
