ui(grid): fix RenderFlex overflow during DataGridCalcBar collapse animation #1641

Problem

In lib/features/workspace/data_grid_calc_bar.dart, DataGridCalcBar uses an AnimatedContainer to animate its height between 26 and 0 when selection statistics appear or disappear:

return AnimatedContainer(
  duration: duration,
  curve: curve,
  height: visible ? 26 : 0,
  clipBehavior: Clip.hardEdge,
  child: material.Row(...),
);

During the collapse transition, the container's height continuously decreases from 26 to 0. However, the inner Row and its child badges have an intrinsic height of ~20px. When the animated height drops below ~20px, Flutter throws:
A RenderFlex overflowed by X pixels on the bottom.

Change

Use QueryaAnimatedExpand (lib/core/motion/querya_animated_expand.dart) or substitute the collapsed state with const SizedBox(width: double.infinity, height: 0) so that the child row is not squeezed below its intrinsic minimum height during the collapse animation.
