The grid and Gantt views were updated to use a newer internal display mechanism. This prepares these views for upcoming work while keeping the visible user experience essentially unchanged.

The hook useVirtual has been replaced by a new hook useVirtualGrid. We

This is done in preparation of task `3601456`.
