Rename AbstractButton's page-tab flag to list-item (setIsListItem / isListItem), so a flagged button reports the ListItem role instead of PageTab - mirroring how the menu-button flag maps to ButtonMenu. A list of items matches NVDA's native single-selection list behaviour better than a tab control for the chat-folders strip. Add an explicit opt-in, RpWidget::accessibilitySelectionList() (default false), for a single-selection list whose accessible focus tracks its selected item. When set, Ui::Accessible::Widget exposes QAccessibleSelectionInterface and forwards container SetFocus/focusChild to the selected child - keyed on the opt-in, NOT on the List role, so plain lists (e.g. message history, which keeps focus and selection separate) are unaffected and don't advertise a single-selection interface whose clear()/unselect()/selectAll() always fail. select() invokes pressAction() - a list item only implements pressAction, not the toggleAction() Qt's default ListItem path would call - and rejects items that are not selectable, so a locked folder is never claimed as a successful selection. A locked folder reports selectable = false.
