Easier widget reordering and steadier chat

Dashboard

• Reordering your dashboard widgets now feels smoother. The drag handle is more responsive, and the widget you are moving stays in place visually instead of leaving a ghost behind.

Chatbot

• The chatbot can now show radar, radial bar, scatter, and composed charts when you ask about your finances. More chart types means it can pick the style that best fits the numbers.
• The chatbot's full-screen view got a visual cleanup, and charts now show a clear empty state when there is nothing to display yet.
• Chat connections are more reliable after switching to token-based authentication for the chatbot's backend API.
• The Copia Assistant now works properly on mobile. The chat view was clipped or hard to scroll on smaller screens, and messages could disappear while history loaded. Both are fixed, and if a connection error happens you will see a notification instead of a silent failure.
