Add Puppeteer scripts for navigation testing and debugging

- Created nav-debug.cjs to log anchor tags and simulate clicks on the Voice navigation link, capturing click events and page navigation.
- Added nav-test.cjs to test the Voice link click and log the URL at various intervals, capturing any page errors.
- Introduced nav-test2.cjs to check the presence of specific elements on the /voice/ page and log any console errors.
- Implemented nav-test4019.cjs to monitor network requests and responses related to the Voice navigation, verifying button presence and click functionality.
