🧪 How Has This Been Tested?

Manual Testing

1. Added a few transactions (Income and Expense).
2. Deleted a transaction and verified that the "Undo" option appeared.
3. Clicked "Undo" within 5 seconds → Transaction was restored successfully.
4. Waited for the Undo timeout → Transaction remained deleted.
5. Verified data persistence after page refresh (localStorage updates correctly).

• Edge Cases
  • Deleted multiple transactions quickly → Only last deleted transaction was restored.
  • Checked that Undo does not create duplicates.

Hello @sharon44-ham

I have reviewed your PR and find out that you have done lots of changes in the files while working on undo transaction. I don't think that all these file need the changes or maybe the changes made while resolving the conflicts.

Please explain why did you update the react and react dom package.

Directly upgrading the react version will affect the overall project and some functionality stops working. It's not required here.

Also, in the Dashboard.jsx lots of code are removed. Please check it and make sure that someone else code doesn't removed by you even unintentionally.

Please check the above points as soon as possible and update us.

Thanks
