Fixed #36935 -- Added fallback in ContentType.app_labeled_name when model_class() is None.

2026-02-21T14:37:46Z

Updated ContentType.app_labeled_name to include the app_label in its string representation. This removed ambiguity for content types whose models were not present in the current codebase (for example, when multiple applications share the same database). Adjusted related tests to reflect the new representation.

Fixed #35545, Refs #32833 -- Fixed ContentTypeManager.get_for_models() crash in CreateModel migrations.
