animatedheightwidget: prevent viewport scrolling

The search field moves upwards and becomes obscured when pressing navigation keys like the down arrow. This happens because the underlying QScrollArea processes keyboard navigation events, shifting the visible viewport even when scrollbars are completely hidden and disabled.

Move the event filter from the contents container directly to the QScrollArea (m_contentsContainerParent) and its viewport. Update the filter to intercept Qt::Key_Up and Qt::Key_Down events, preventing the scroll area from handling these inputs.
