- Some minor CSS style changes were needed for errors on the email debug screen. Also we weren't showing any message i - for whatever reason - there was no data for batches.

- The length of the error messages for temporary and permanent failure tabs on the email debug screen can be arbitrary. This degrades scannability and limits the number of displayed rows in the list. Adding an expand button to the error message makes sense since the errors might repeat and the error code + the beginning of the message can be enough to understand them. Also this allows more rows to be displayed per screen.
