fix: move router to api layer and add missing imports/guards

- Move APIRouter definition from instance_service.py back to tool_instances.py
  (service files should not define FastAPI routers)
- Add missing prepare_manifest_instance import in tool_instances.py
- Guard repo.remote_url before clone_repository call
- Guard tool_type.compose_template before render_compose_template call
- Rename subprocess result variable to avoid shadowing SQLAlchemy Result
- Build error message as local string to avoid None/bool type issues

Quality gates: py_compile pass, LSP clean
