💡 Background and solution

When a table has aggregation rows and a column is configured with cellType: 'radio', the radio button incorrectly appears in the aggregation row. However, checkbox type cells correctly fall back to plain text cells in the same scenario.

Root cause: In packages/vtable/src/scenegraph/group-creater/cell-helper.ts, the checkbox branch checks isAggregation && isSeriesNumber to decide whether to render a text cell instead of a checkbox, but the radio branch was missing this conditional check.

Solution: Added the same isAggregation && isSeriesNumber guard to the radio branch in createCell(). When the cell is in an aggregation row and is a series number column, it now renders as a plain text cell using createTextCellGroup instead of createRadioCellGroup, consistent with the checkbox behavior.
