Merge branch 'dev/appdata-wrapper-fix' into 'main'

    <description><![CDATA[in /e/OS cloud, nextcloud accounts are linked to mail accounts. This app ensures both are coordinated: it sets the e-mail address, quota and storage of the user upon creation.

    It also completes the account deletion by cleaning other parts of the /e/OS cloud setup to ensure no more data is retained when a user requests an account deletion.

    This app uses the UserDeletedEvent to invoke scripts in the docker-welcome container of /e/OS cloud setup]]></description>
