feat(core): rewrite "Empty Data" warning component to be in the canvas

[ghiscoding]

• remove all the previous absolute position as it was causing too many issues
• instead create a component and place it within the grid-canvas on both left/right viewports which will work for both regular/frozen grids and also add options to hide any of the 2 sides when using frozen grid
