fix(notification): address review suggestions

- ChronikFuerDichBox: move update() inside the failure branch so success
  path skips it, matching NotificationDropdown's pattern
- NotificationDropdown test: add role=alert assertion for mark-all-read
  failure to match existing dismiss-failure coverage in ChronikFuerDichBox
- +page.server.ts: use getErrorMessage(undefined) instead of null so the
  missing-notificationId 400 goes through the same i18n pipeline as other errors
