Features: 1) Add @extend_schema_field for get_recently_viewed to improve OpenAPI schema generation.

Fixes: 1) Correct logic in `get_recently_viewed` method to properly handle `recently_viewed` items.

Extra: 1) Add missing import for `drf_spectacular.utils.extend_schema_field`; 2) Update method docstring for clarity; 3) Adjust typing in `get_recently_viewed` to use `List[Dict[str, Any]]`.
