Main changes:
Use assertContains instead of assertTrue(text.contains) for better error messages on failure
POI 61007, use CellFormat for all format strings containing multiple parts (";" delimited) and update unit test to expect the same values as Excel. Also added tests for the failing formats.

testcases/main/HSSF/EventUserModel/TestFormatTrackingHSSFListener.cs:63

• The expected format string for index 42 appears to have been swapped with the one for index 41. Please verify that the change is intentional.

ClassicAssert.AreEqual("_(\"$\"* #,##0_);_(\"$\"* (#,##0);_(\"$\"* "-"_);_(@_)", listener.GetFormatString(42));

main/SS/UserModel/DataFormatter.cs:329

• The condition for handling conditional data formats has been altered from checking for 3+ parts to 2+ parts; please confirm that this change aligns with Excel's behavior and does not inadvertently affect the processing of formats.

if (formatStr.IndexOf(';') != -1 && (formatStr.IndexOf(';') != formatStr.LastIndexOf(';') || rangeConditionalPattern.IsMatch(formatStr)))
