Frontend fixes (#22309)

* prevent unnecessary reloads in useUserPersistence hook

* always render ProtectedRoute (handling undefined roles internally) and add Suspense fallback

* add missing i18n namespaces

react 19 enforces Suspense more strictly, so components using useTranslation() with unloaded namespaces would suspend, blanking the content behind the empty Suspense fallback

* add missing namespace

* remove unneeded

* remove modal from actions dropdown
