tui: surface a dismissible new-interface notice and tighten settings copy for clarity

Users who were migrated to the new interface will now see a dismissible notice in Settings explaining the old interface was phased out, so they are not surprised by the change. The new-interface toggle is also visually elevated with a card style so it is easier to find. Settings labels and descriptions across General have been rewritten to be shorter and more direct, so it is quicker to understand what each option controls. The "New" badge color is also adjusted for better readability.
