fix(table): prevent stale refs during column drag operations

Fix two bugs in column drag-and-drop:
1. Stale columnWidths ref during rename - compute updated widths inline
   before passing to updateMetadata
2. Escape-cancelled drag still reorders - update dropTargetColumnNameRef
   directly in handleColumnDragLeave to prevent handleColumnDragEnd from
   reading stale ref value
