feat: Implement Z3ED Command Callbacks for Proposal Management in EditorManager

- Added Z3ED command callbacks for managing proposals within the AgentChatWidget, enhancing user interaction with proposal acceptance, rejection, listing, and diff viewing functionalities.
- Updated the AgentChatWidget to initialize default chat sessions and improved the chat history popup with new message sending and snapshot capturing capabilities.
- Enhanced the UI of the AgentEditor with a compact tabbed interface for better organization of bot management and session history, improving overall user experience.
