PR Summary

• Updated Name Descriptions for Email Items
  A new data arrangement script, 0053_alter_emailitem_options.py, was added. It modifies the existing description labels for 'EmailItem'. Now, the individual label reads as "Afsendt email", and the collective label is "Afsendte emails".
• Revised Sorting Order for Email Items
  The script also determines the order in which 'EmailItem' records are displayed. Now, they will be shown with the most recently created items appearing first.
• Model Attributes Modification
  The name characteristics in the EmailItem data model have been adjusted. They now align with the changes made in the new script, properly reflecting the revised labels "Afsendt email" and "Afsendte emails".
