public class AiChatInputFragment
extends Fragment<com.vaadin.flow.component.orderedlayout.VerticalLayout>

Reusable chat input ("composer"). Replaces the stock Vaadin MessageInput with a JmixTextArea + send JmixButton, so it can be embedded both in the timeline (AiChatFragment) and on the chat hub screen.

Submit gesture. Enter submits; Shift+Enter inserts a newline. The server-side submit fires only for a bare Enter (DOM keydown filter) and the newline insertion is suppressed client-side via preventDefault.
