Subject: [PATCH] [TASK] Uniform output of FlashMessages in the backend
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* Instead of displaying all `FlashMessages` in a single `alert-warning` container, use the standard template and render an `alert` for its status with an icon for each message.
* Add localization for `BackendConfirmationFlashMessageLogout`, which was previously always displayed in English.
* Remove the `messageTitle` of the backend `FlashMessages` – these were not previously displayed and have not been localized.
