feat(plugins): add duplicate plugin functionality and related API endpoints

- Implemented a new `duplicatePlugin` function to allow copying of installed plugins with a new ID. - Added API endpoint for duplicating plugins, including error handling for various edge cases. - Introduced frontend hooks and UI components for duplicating plugins in the script management interface. - Enhanced tests to validate the duplication process and ensure proper error handling.
