fix(clickTtHttpPageRoutes, clickTtHttpPageService): update effective page URL handling in proxy routes

Browse Source 
- Introduced a new variable, effectivePageUrl, to ensure the correct URL is used for rewriting links and form actions in both GET and POST proxy requests.
- Updated the logic to derive the page origin from effectivePageUrl, enhancing the accuracy of base tag handling for relative URLs.
- Enhanced logging in the fetchWithLogging function to include the response URL, improving traceability in HTTP requests.
