Subject: [PATCH] Change: Hide client chat dialog on close instead of
 terminating

Closing the client-side chat dialog (via the "end chat" button or the title-bar
X) now only hides the window and keeps the session alive, instead of destroying
it. Closing the chat stays server-initiated: the next message from the server
reopens the hidden dialog via the existing SW_RESTORE path in OnReceive, and the
dialog is only truly destroyed on COMMAND_CHAT_CLOSE or connection close.
