Feature/edit delete messages

[Redesu]

• Add core functionality for editing and deleting messages
• Add buttons to the UI that allow the user to edit and delete messages
• Users can edit and delete messages.
• Edited/deleted data persists on the backend.
• Editing a user message should trigger an llm service call.
• Editing an assistant message should not trigger an llm service call.

Adds 2 buttons for both assistant and user messages, user can delete and edit the messages. It persists on the backend.

Delete

Edit

If its a assistant message, it is not triggering the llm service

If its a user message, it triggers the llm service and puts the message bellow the existing message

Warning

Right now it is keeping both old and new messages from the LLM. Changes can be made if decided to delete the old one

Since both send and edit messages uses stream, a new function was made for a cleaner code.
