    client: conversation-list: Migrate from `TreeView` to `ListBox`
    
    - Replace ConversationListStore with ConversationListModel
    - Get ListBox rendering
    - Implement proper multiselection for ListBox
    - Build row widget
        Unread status
        Multiple sender addresses
        Per-sender unread styling
        Buttons for mark as read and flag
        Allow disabling preview
        Occasionally update timestamp displays
    - Build List widget
        Port all selection (get/set/etc) APIs
        Build ListModel for subscribing to ConversationMonitor
        Context Menu
        Use Gestures when possible
        Drag and Drop
    - Build Scroll widget
        load more when scroll reaches near bottom
        Report currently visible conversations
