Implement Message Editing Feature in Chat

[Shruti-1910]

Description:

Currently, the app does not support message editing in chat conversations. Message editing is a fundamental feature that allows users to correct mistakes, clarify thoughts, or update information without having to delete and resend messages. Implementing message editing will enhance user experience and communication flexibility within the chat feature.

Expected Behavior:

• Users should be able to edit messages they have sent in chat conversations.
• Edited messages should update in real-time for all participants in the conversation.
• There should be clear indicators (e.g., timestamp or notation) to show when a message has been edited.

Acceptance Criteria:

1. User Interface:

• Implement UI elements (e.g., edit button or gesture) to initiate message editing.
• Provide a text input field or modal window where users can make changes to their messages.

2. Functionality:

• Implement logic to allow users to edit their messages securely and efficiently.
• Ensure that edited messages update in real-time for all participants in the chat conversation.
