Creating/renaming/deleting a folder in ConversationListView only ever
updated its own local @State — the sidebar has a separate folders
array that was only refreshed by onAppear or conversation-change
triggers, so a folder created in the modal didn't show up in the
sidebar until the next app launch. Sidebar now reloads when
showConversations transitions to false (the modal closing).
