feat: add Python service connection testing functionality

- Implemented a new IPC handler in the Electron main process to test connections to a Python service.
- Updated the preload script to expose the new connection testing method to the renderer process.
- Modified the Vue component to utilize the new method for checking the Python service connection, enhancing user feedback on connection status.
