Wrong Data Format (String) corrupts formatted values

Library version 5.5.1:

cell, having number cell style defined as
`#.##0,00 _€;[Red]-#.##0,00 _€ `
returns
`#,##0.00_);[Red](#,##0.00) `
on call to cell.getCellStyle().getDataFormatString - it corresponds to built-in style 40 (0x28)
negative values, formatted with this format by call to
`DataFormatter.formatRawCellContents`
return positive values in round brackets, so the value is effectively corrupted while using streaming event mode with XSSFSheetXMLHandler.

Here is the full code and sample file [poi_formatting_problem.xls](https://github.com/user-attachments/files/24216439/poi_formatting_problem.xls) to reproduce the issue
```

try (var wb = WorkbookFactory.create(new File("poi_formatting_problem.xls")))
{

//Style (as seen in Excel) #.##0,00 _€;[Red]-#.##0,00 _€
//is converted to #,##0.00_);[Red](#,##0.00)
var sheet = wb.getSheetAt(0);
var row = sheet.getRow(0);
var cell = row.getCell(0);
var str = new DataFormatter().formatRawCellContents(cell.getNumericCellValue(), cell.getCellStyle().getDataFormat(),

cell.getCellStyle().getDataFormatString());
//str is (378.13) instead of -378.13
}

```

Start with DataFormatter.formatRawCellContents and the style/data-format handling shown in the reproduction, using WorkbookFactory to inspect the supplied sample file. Compare the format returned by getCellStyle().getDataFormatString with the original Excel style and verify the negative value through the streaming XSSFSheetXMLHandler path; done means it remains negative rather than appearing in brackets.
