.xls (Excel 97-2003) import used only each cell's number format. It now also reads the BIFF8 formatting records (Font, XF, Palette and Style), so opened sheets keep their fonts, solid and pattern fills, borders (including diagonals), alignment (rotation, indent, wrap, shrink), locked and hidden protection, the workbook's custom colour palette, its Normal font as the default, and its user-defined cell styles. The decoding lives in a new xls/styles.rs; xls/mod.rs gains the record arms and the build call. Short or malformed formatting records keep the fields present and add one warning instead of refusing the workbook. Tests build the records in code, including truncation and byte mutation. Also merges origin/main, keeping its dialog-sheet, WINDOW2 and XF number-format handling; the XF arm now goes through the new styles module, which covers the number format too.
