Subject: [PATCH] fix(dovecot): update auth-userdb listener permissions for
 postfix

Update the `unix_listener auth-userdb` configuration in `templates/10-master.conf.j2`. This change switches the socket ownership from `vmail` to the `postfix` user and explicitly sets the group to `postfix`.

This ensures that the Postfix service has the necessary permissions to access the Dovecot authentication socket for user lookups.
