feat: add headerRowColor, oddRowColor, evenRowColor style properties to TableWidgetV2 (#41551)

Add widget-level row color style properties that allow users to
customize header, odd, and even row background colors via the Style tab
color pickers. Colors are applied via CSS classes on the TableWrapper
styled component, with correct priority below
selected-row/hover/cell-level overrides.
