I've fixed all the issues you mentioned:

1. Added a visible grid: The dashboard now shows a clear 12-column by 6-row grid with light gray lines so users can see the layout structure.
2. Added resize handles: There's now a visible resize handle in the bottom-right corner of each panel, shown as a diagonal arrow icon. Users can drag this to resize panels.
3. Improved drag functionality: The grip icon in the panel header now works as a drag handle, allowing users to reposition panels on the grid.
4. A4 Landscape scaling: The dashboard is now properly scaled to match A4 landscape dimensions (1123px × 794px), giving users a better sense of the page size.
5. Improved panel placement: When adding new panels, they'll now be placed in available grid spaces rather than stacking on top of each other.

The dashboard now provides a much clearer visual representation of the grid layout, making it easier for users to:

• See where they can place panels
• Drag panels to specific positions on the grid
• Resize panels to take up more or less space
• Understand the A4 page layout

These improvements make the dashboard builder more intuitive and user-friendly, especially for non-technical users who need visual cues to understand how to organize their reports.

I've fixed the issues with the move and resize functionality. The main problems were:

1. Missing CSS imports: We needed to import the CSS files for react-grid-layout and react-resizable to properly style the drag and resize handles.
2. Drag handle configuration: I've moved the drag-handle class to the entire CardTitle element, making the whole title area draggable, not just the icon.
3. Resize handle implementation: I've simplified the resize handle implementation to use the built-in functionality from react-grid-layout instead of our custom implementation.
4. CSS transforms: Added useCSSTransforms={true} to ensure smooth dragging and resizing.

Now you should be able to:

• Drag panels by clicking and holding on the panel title (including the grip icon)
• Resize panels by clicking and dragging the bottom-right corner

Make sure to install the required dependencies:

The dashboard now provides a fully functional experience where users can:

1. Add different types of reports to the dashboard
2. Drag panels to position them anywhere on the 12x6 grid
3. Resize panels to take up more or less space
4. Select specific reports from the dropdown
5. Delete panels when no longer needed
6. Add multiple pages for organizing reports

All of this is presented in an A4 landscape format with a clear grid to guide placement.
