refactor(desktop): move commons/ui/chat into desktopApp

Every file under commons/src/commonMain/kotlin/.../commons/ui/chat/
(ChatBubbleLayout, ChatMessageCompose, ChatroomHeader,
DmBroadcastBanner, DmBroadcastStatus, UserDisplayNameLayout) was
imported only by desktopApp. Android has its own parallel
implementation at amethyst/.../chats/feed/, so nothing shared.

Moved the six files into desktopApp/.../ui/chats/ alongside
ChatPane.kt, DesktopMessagesScreen.kt, etc. — same package as every
existing caller, which lets us drop six `import` lines from
ChatPane.kt + DmSendTracker.kt + DesktopMessagesScreen.kt. Empty
commons/ui/chat/ directory removed.
