Fix #6652: Extend grab selection to include BBIM_Array members (#7968)

When grabbing an array child, the selection now expands to include
the array parent and all sibling children before the move operator
runs. Mirrors existing behavior for aggregates and nests.

Generated with the assistance of an AI coding tool.
