Previously, CreateRepo submitted the PLC DID before the remaining local setup steps had completed. If RBAC setup or hook installation failed after that point, the handler cleaned up local state but still left behind a published DID with no corresponding repo on disk. Move PLC submission to the end of the create flow so the DID is only published after local repo setup succeeds. Also roll back repo RBAC state during cleanup, and treat hook setup failure as fatal instead of silently continuing.
