    fix(sqllab): preserve whitespace in grid result cells
    
    ag-Grid's default cell style collapses runs of whitespace, which
    misrepresents whitespace-sensitive values such as option symbols in
    query/result tables. Apply white-space: pre to .ag-cell-value so the
    displayed value matches the underlying data.
    
    Fixes: #36042
