UI/Qt: Add tab hover previews
Show a delayed preview popup when hovering background tabs. Build the thumbnail from the cached front or backup WebContent bitmap so chrome does not need a fresh screenshot request or WebContent repaint on hover. Tie the popup to the tab hover lifecycle and hide it on current-tab hovers, tab presses, drags, layout changes, and tab strip exits.
