feat(clickTtHttpPageRoutes): add meta-refresh URL rewriting for proxy handling

- Implemented a new function to rewrite meta-refresh URLs in HTML, ensuring redirects after login are routed through the proxy while maintaining session integrity.
- Updated the proxy GET and POST endpoints to include the new meta-refresh handling, enhancing the overall functionality of the proxy interactions.
- Improved error handling in the new function to ensure robustness in processing HTML content.
