feat: add archived application text field to EinundzwanzigPleb model

This commit introduces a new field `archived_application_text` to the EinundzwanzigPleb model. The application text of a Pleb is now archived before the association status is updated and the application text is set to null. A migration file is also added to update the database schema.
