[dhairyashiil]

As an EmbeddedChat developer

I need to: Implement Message & Chat Input UI Enhancement for Edit Message Functionality

So That: Users can have a better UI Experience when editing messages.

Acceptance Criteria

• When a message is clicked to be edited, its background color changes dynamically to indicate it is being edited.
• The background color of the chat input box matches the edited message's background color.
• The implementation dynamically handles light and dark themes, ensuring appropriate color contrast for both.
• Ensure smooth transition between color changes for both message and chat input box.
