feat: enhance image handling in chat and drop zone components

- Updated ImageAttachment interface to make 'id' and 'size' optional for better compatibility with server messages.
- Improved image display in AgentView for user messages, including a count of attached images and a clickable preview.
- Refined ImageDropZone to conditionally render file size and ensure proper handling of image removal actions.
