Cover paneTitle propagation with ThreadsScreen and ChatsScreen tests

ThreadsScreenTest is a new Robolectric Compose UI test class that follows the ChannelsScreenTest / ChatsScreenTest pattern: mocks the chat client + state, renders the screen with default and custom titles, asserts the header text. ChatsScreenTest gains an equivalent custom-title case so the new remember(listContentMode, title) key path is exercised.
