feat: Add GUI Automation Tool for Tile Placement

- Introduced the HandleGuiPlaceTileCommand function to facilitate tile placement via GUI automation, enhancing the tool's capabilities for user interaction.
- Updated the ToolDispatcher to include the new command, allowing for seamless integration into the existing command structure.
- Enhanced the AgentChatWidget to initialize default labels for resource tools, improving the user experience with visual feedback on label loading status.
- Improved error handling and user messaging for better clarity during tile placement operations.
