feat(P5B.T6): composer Spielen button + bubble dispatch + game-picker
Wires mini-game entry points: createGamePayload helper in conversationFeatures.ts (GamePayload import added), game state/handler/picker-dialog/modal-mount/open-event-listener in ConversationPage.tsx (DM-only guard uses conversation.members[].userId camelCase as confirmed), and parsed.kind==='game' bubble branch in MessageBubble.tsx dispatching chatapp:open-game CustomEvent.
