Chat Widget v6 - Support Real-Time Theme Switching for Chat Widget Programmatically

Currently, the CometChat Chat Widget automatically applies its theme based on the configuration from the Dashboard or Browser’s default theme if system is chosen in the dashboard. However, developers have no way to programmatically update the widget’s theme at runtime. This creates a limitation for apps that implement their own theme switchers and want the chat widget to stay in sync with the rest of the application’s UI.
