* fix(settings): size the unused downloads list to its real rows The list reserved 56px per row, but a row renders taller than that once its margins and the Delete button are counted. With two leftover models the header read "2 leftover models" while only the first row fitted in the viewport, and the second could neither be seen nor deleted. The overlay scrollbar gave no hint either, since it stays invisible until hovered. Measure the list once its rows are in place and cap that at the existing 220px, and keep the scrollbar in the layout so a list that does reach the cap looks scrollable. * fix(settings): test the list sizing without reimporting the dialog Review follow-ups on #686. The test helper popped vocalinux.ui.settings_dialog from sys.modules at collection time and reimported it under a patched Gtk, restoring only sys.modules and not the attribute on the package. Whichever module object a later test reached then depended on collection order, which is why test_model_deletion::test_whisper_list_and_delete failed on 3.9/3.10 with assert [] == ['tiny'] while main stayed green. Move the arithmetic into a module-level _clamp_unused_downloads_height() and unit-test that directly, the way _list_downloaded_whisper_models is already tested. Nothing touches sys.modules now. The dialog cannot be instantiated under the mocked-GTK harness, so the wiring the old tests never covered is asserted against the method source, following test_settings_mode_change.py: refresh calls the fit, the fit measures the listbox and feeds set_min_content_height, the per-row estimate stays gone, and the scrollbar stays out of overlay mode. * fix(settings): remeasure the unused-downloads list when it expands The refresh measures while the expander is collapsed and the dialog may not be mapped; if that first measurement ever comes back short, the expand handler remeasures so the rows cannot stay clipped.
