feat: Refactor UI Layouts and Enhance Visibility in AgentChatWidget and AgentEditor

- Restored a compact single-row layout for the AI provider selection in AgentChatWidget, improving visibility and accessibility.
- Removed redundant RenderAgentConfigPanel to streamline the UI, ensuring the connection header is always visible.
- Updated the collaboration panel to be always visible, enhancing user interaction without the need for collapsing headers.
- Modified the AgentEditor layout to feature a three-column design with always-visible settings and status cards, improving organization and user experience.
- Enhanced the chat history popup with a more compact title and provider dropdown, ensuring buttons are properly spaced and functional.
