auction system fails to send the winning email since 19th of April. From the error message looks like a data issue.

error management needs improving - problem with a single data entry should not stop the process for all. Also if possible there should be some kind of notification to admin about failing processes as in this case it was the end user that notified us about not receiving the winning email.

we have determined that all emails for auction finished at the end of 18.apr got all the notifications as expected and none of the winners starting from 19th Apr auctions have not received the winning notification. Last production update to auction system was on 19th so probably related to that update: https://github.com/internetee/auction_center/releases/tag/240411. Apparently all the other notification still work including the messages to participants that did not win.
