fix(favorites): bulk un-favorite without the UI freeze, with feedback

- Local Library bulk un-favorite was O(selected x visible) on the UI thread and froze on big libraries (owner: 'se ciclo'). Now: one model pass (hearts hollow instantly), store mutations on a blocking thread, 'Removing…' info toast up front and a success toast at the end. - Favorites > Tracks bulk remove: 150 ms courtesy delay between Qobuz API calls (no burst) + the same progress toasts. km
