    chore(lint): convert dashboard components to function components
    
    Converts Dashboard, DashboardGrid, SliceAdder, DragDroppable,
    FilterScopeModal, FilterScopeSelector, gridComponents (Chart, Divider,
    Header, Markdown, DraggableNewComponent), menu components (HoverMenu,
    BackgroundStyleDropdown, MarkdownModeDropdown, WithPopoverMenu),
    nativeFilters (FilterValue, DefaultValue), PublishedStatus, and
    UndoRedoKeyListeners from class to function components.
