feat(ecobot): introduce backdrop click dismissal & streamline header UI

[toufiq00007]

🚀 Description

Refactors the interaction model of the floating EcoChatbot component. It permanently removes the manual close (X) button from the header layout and replaces it with a backdrop overlay, allowing users to dismiss the chat widget by clicking anywhere in the empty viewport space.

🛠️ Changes Made

• Backdrop Click Dismissal: Added a full-screen, invisible interactive backdrop layer (fixed inset-0 z-40 bg-transparent) right beneath the chat container. Clicking this layer sets isOpen to false, seamlessly dismissing the widget.
• Component Decoupling: Wrapped the layout inside a React Fragment (<>...</>) to handle both the backdrop overlay and the chat card as side-by-side elements under the isOpen state.
• Header Simplification: Permanently removed the manual close icon and wrapper button from the chatbot header container to streamline the interface.

🧪 Verification

• Verified that clicking on the chat container itself does not close the widget.
• Verified that clicking anywhere on the layout background outside of the widget successfully triggers the close animation.
• Confirmed that all JSX tag hierarchies match up properly and the codebase compiles with zero TypeScript errors.
