#874 fixup: import get_wishlist_service in the ignore-list endpoints

ruff F821 caught a real NameError: the three /api/wishlist/ignore-list*
endpoints called get_wishlist_service() without the local import every
other call site in web_server.py uses, so they'd crash the moment the
Ignored modal queried them. Add the import; ruff check now clean.
