Add tool duplication functionality and enhance ComponentsToolsPage

- Implement a new API endpoint for duplicating tools in the backend.
- Add a duplicate_tool function in ComponentsToolsPage to handle tool duplication requests.
- Update the UI to include a dropdown menu option for duplicating tools, improving user experience.
- Refactor the remove function to accept a resource object instead of an ID for better clarity and maintainability.
