[Mazharcodemaster]

Description
The chat module lacks several essential messaging features that are standard in modern chat applications. Adding these will improve usability and user experience.

1. Missing Features (to be developed):
2. Ability to edit and delete sent messages.
3. Support for attachments (files/images).
4. Online/offline status indicators for users.
5. Typing indicators to show when a user is typing.
6. Latest active chat/user should appear at the top of the chat sidebar (similar to WhatsApp).

Expected Result:

1. Users can edit and delete their own messages.
2. Users can send/receive attachments (files/images).
3. Presence (online/offline) indicators are visible.
4. Typing indicators are displayed in real-time.
5. Chat sidebar dynamically updates to show the latest active chat/user on top.
